VTDownloader UI Refresh

Added

• Companion mod: the refreshed download screen as its own mod, requiring VTDownloader 2.6.0 or newer. Takes over wherever VTDownloader opens its screen. Remove it to get the original back.
• Installed: a row at the bottom of the sidebar lists the packs in the Vanilla Tweaks zips in your resource pack folder. Chips at the top show one zip at a time.
• Keyboard: the arrow keys move over the packs, and Space or Enter selects one. Cmd/Ctrl+1 to 9 open a category. Ctrl+Tab and Ctrl+Shift+Tab move through the sidebar.
• Pack pages: the arrow on a pack opens its preview, animated GIFs included, its whole description in the colours Vanilla Tweaks gives it, and the packs it can't be used with. Previews are kept in cache/vtd_ui_refresh/previews.
• Icon cache: pack icons are kept in cache/vtd_ui_refresh/icons, so they download once per Vanilla Tweaks version.
• Range selection: shift-click selects or deselects every pack from the last one clicked, in the list or the grid.
• Select all: Cmd/Ctrl+A selects every pack in the list, or deselects them if they're all selected. Cmd/Ctrl+Shift+A deselects everything. Neither acts while a text field has focus.
• Search: Cmd/Ctrl+F searches names and descriptions across all categories.
• Side panels: drag either edge to resize, or to the window's edge to hide. An arrow brings a panel back.
• Back and forward: buttons, Cmd/Ctrl+[ and ], and the mouse's side buttons. Each returns to where the list was scrolled.
• Grid view: a choice of list or tiles, remembered between sessions.

Changed

• Subcategories: rows after their category's packs, with a few of their icons, or boxes in the grid.
• Descriptions: a list row shows two lines, and a pack's page the rest. Packs have no tooltips. Category warnings show all of their text.
• Popups: the share and error popups draw above the list, with room around the text.
• New look: Vanilla Tweaks orange on black, a vertical category sidebar, and a cleaner reload icon.

Fixed

• Selected packs: deselecting the last pack of a subcategory no longer leaves its category heading behind, drawn over the next one.
• Hex warning colours: the new screen reads colours like #242423, which crash VTDownloader's own screen.
