Dimensional Flux Miner

Add creative tanks, REI, and GUI refresh

✨ Added

• ⚪ White icons, the new default: the machine screens now show white icons unless you pick Blue or Purple in the Settings window. The energy bar, the volume bar and the terminal text stay blue with white icons. Settings saved with Purple keep Purple; everything else starts on White.
• 📕 REI support (optional): the same Crushing, Electric Furnace (Furnace) and Electric Furnace (Alloy) pages as in EMI and JEI, drawn with the machines' own elements; clicking a machine's work chamber opens them, and R / U work on the items inside machine slots. The pages follow REI's light or dark theme (slots, energy and heat parts darken with it). With EMI installed, EMI is used; with REI and JEI, REI.
• 🪟 Recipe viewers make room: the side tabs and the open windows of the machine screens (also while you drag a window over them) push EMI, JEI and REI's item lists out of the way instead of being covered.
• 🛢️ Creative Dimensional Tank (creative mode only, no recipe): one chamber of endless liquid for building and testing. The creative tab and EMI, JEI and REI list one already filled with each liquid of the game; pouring a liquid into an empty one picks it. Buckets, pipes and Auto Eject take as much as they want and it never runs out; while empty it voids what pipes send. It has no channels (no code, no personal code): sneak and use it with an empty hand, or press Empty on its screen, to empty it. Breaking it keeps the liquid on the item. In the inventory and the recipe viewers its icon shows the liquid inside.
• 🪣 Tank items carry their liquid (Dimensional Tank and Creative Dimensional Tank, not the dual tank): used on a tank, in any mode, the item fills it with as much as fits (the channel's liquid, or the endless creative one; a creative tank fills a whole Dimensional Tank at once). Bucket mode (sneak and use the item in the air to switch it): the item is not placed, it pours its liquid on the ground one bucket at a time (sneaking always pours) and picks up the liquid source you look at. Sneaking with a tank item against a tank places it.
• 🧹 Empty a channel: the code window of the Dimensional Tank and the Dual Dimensional Tank has an Empty button (one per chamber on the dual tank) that deletes the channel's liquid for every tank with that code. It takes two clicks, so it is not pressed by accident.
• 🔎 The creative tanks are also in the Tools and Utilities tab, right after the milk bucket, so searching a liquid in the creative inventory shows them right after its bucket.

🔄 Changed

• 🔘 New buttons: every button of the machine screens (tabs, windows, side configuration) has a new look: dark outline that turns cyan under the mouse, light border and slate inside; a switched-on button (toggle on, open tab) is gray and sunk, like one that cannot be used. The dark screens darken them too. With purple icons the outline under the mouse is purple.
• 🗂️ Side configuration tabs stay in place: every material tab (Items, Energy, Fluids...) is always shown in its own spot, the open one grayed like the tab of an open window, instead of the open tab disappearing (on the Miner the Energy tab used to turn into the Items tab).
• 🪟 Glass read-outs: the black terminal boxes of the screens (Miner status, tank contents, the automation line of the side windows, the Miner's filter and the info windows) are now glass viewports in the screen's own metal, sunk into the panel with rounded corners, a navy glass (dark purple with purple icons) and a faint diagonal reflection like the liquid gauges. The Miner's read-out has a status lamp (green while mining, orange when stopped, blinking amber while waiting, blinking red without a Core) and the tank read-outs are larger, with a small lamp in each stored liquid's color beside its name (unlit while empty). The Problems tab shows its yellow warning sign on a matching glass button, lined up with the other tab buttons.
• 💧 Dimensional Tank gauges: each chamber is now shown as a liquid gauge that matches the energy bar: a framed bar with level marks, the liquid in its own texture and color, and a moving reflection over it.
• The material tabs of the side configuration windows are larger and no longer have a colored ring (the icon tells the material).
• Stacked side tabs have a little more room between their buttons, and the Upgrades and Settings icons sit 1 px lower, centered on their buttons.
• 🛢️ Liquid fills the tanks to the glass: the liquid inside the Dimensional Tanks (single and dual) now reaches the windows instead of floating in the middle with a gap around it. Full Changelog: https://github.com/vindocel/Dimensional-Flux-Miner/compare/v0.2.7+1.21.1...v0.2.8-beta.1+1.21.1
