v1.0.7: Small bugfix release (with some small QoL tweaks)

A bit overdue, but here's another small bugfix release... the third in a row that fixes a bug that only appears in External In-Flew-Ences. That level is cursed, I tell ya... don't play it without some fresh garlic on hand.

• Fix potential "data structure not found" error when hitting blocks in multi-room levels (i.e., only External In-Flew-Ences) after restarting from checkpoint. (I couldn't reproduce it or figure out what could cause it, so the root cause isn't gone; but there's enough error handling that it won't crash the game anymore)
• Shop and Inventory menus now have elemental icons for powerups that differ only in color (fire icon on Fire Mecha Ball, electric on normal Mecha Ball, etc) to improve accessibility. (I always felt kinda bad about that but didn't know how to improve it)
• You can now control your movement during a Hikkori Skull dash, which makes it harder to drop yourself into a bottomless pit and allows non-Matt characters to essentially double jump.
• Damaging an enemy with Hikkori Skull dash now curses them, causing them to take damage over time for a while. This should make the attack much more reliable against normal enemies.
• Touch up Matt's sprites a bit (doesn't have bare chest for cat / dragon transformation anymore). It didn't look particularly hot and also didn't fit his character.
• Recolored Mecha Ball powerup to be the same green color as the armor, which is more consistent with the Fire Mecha / Ice Mecha and also makes it harder to mix up the Boom Ball and Mecha Ball powerups.
• Linux version has a proper icon (should show up in the Ubuntu sidebar but not affect the executable itself)
• Linux version texture page size changed to 1024x1024 (was 4x that originally), should increase compatibility and lower load times a bit.
• Linux version information text changed from the Game Maker defaults. (I didn't realize the information settings weren't shared between platforms)
