Immaterial Drawers

Two new kinds of drawer, each arriving with the mod it belongs to, and two fixes every 0.1.0 player should have.

Added

• Chemical Drawers, when Mekanism is installed: gases, infuse types, pigments and slurries, in the three layouts Functional Storage gives its fluid drawers (1x1, 1x2, 2x2), each with a framed twin. Same capacities as the fluid drawer beside them, scaled by the same storage upgrades; same fill order, locking, void and creative. Pressurized tubes connect from any side, and a Storage Controller or extension exposes every chemical tank on its network. Right-click a slot with a chemical tank to empty it in, left-click to fill it back.
• They look like the fluid drawer, in the graphite family of the energy drawer, with a teal window where energy has copper. Gases glow and their surface slowly breathes; heavier chemicals sit still like a fluid.
• Without Mekanism nothing changes: the blocks are not registered, no Mekanism class is loaded, and the recipes are conditioned on it.
• Source Drawer, when Ars Nouveau is installed: a drawer of Source, framed or not. Relays connect to it through Ars's Source capability, and everything that draws Source from nearby - the enchanting apparatus, imbuement, sourcelinks filling it - finds it the way it finds a Source Jar. 32,000 Source unupgraded, over two billion with four Netherite upgrades. A Storage Controller exposes the Source of its whole network to a relay. Violet-rimmed, with Ars's own Source glowing inside.
• A switch per feature in the config - Energy Drawer, Chemical Drawers, Source Drawer, Wireless Charger. Off means no recipe and no creative-tab entry; drawers already placed keep working, and worlds and multiplayer are unaffected.

Changed

• A new logo showing the whole family - the energy drawer's cube, a chemical drawer, a source drawer and a 2x2 chemical drawer - instead of four energy drawers.
• The Wireless Charger has a new face: Functional Storage's own utility-upgrade plate and port, with copper wave arcs and a lit port, instead of a flat dark tile that belonged to no mod.

Fixed

• Right-clicking or left-clicking the front of an Energy Drawer with anything in hand threw on the server (Slot 0 not in valid range - [0,0)). Functional Storage offers the held stack to the drawer's item handler at the slot that was clicked, and the empty handler validated that index. It is now NeoForge's EmptyItemHandler, which has no slots and does not mind being asked.
• Breaking an Energy Drawer dropped nothing - not the block, not the energy in it, not its upgrades. The drawers need the correct tool to drop, and were in no mineable tag, so no tool was correct. Every block of the mod is now generated into minecraft:mineable/pickaxe, like Functional Storage's own drawers.

Notes

• Mekanism and Ars Nouveau are optional dependencies, declared as such. Tested with both, with one, and with neither: 52 game tests with both installed, 21 with neither, and no Mekanism or Ars class is ever loaded without its mod.
• Tested through the other mods' own blocks, not only through our code: a Mekanism pressurized tube moving chemicals between two drawers, a Mekanism universal cable moving energy, an Ars Nouveau relay moving Source - each checked to create nothing on the way.
• Botania mana is planned, and waits for a Botania release on 1.21.1.
