Standardized the way addItemDef works. It now always checks if there's an item with the same id in stores.

Generation option masks now operate by value, rather than string.
Fixed that an inverted requirement only worked if set to nil instead of false.
For finer control over masks, you can replace the requirement field with the raw and passFunction fields in the masks and requirements tables respectively.
- raw, if set to true, causes the value of the option to be saved to the masks table, rather than a simple true/false.
- passFunction should be a function that takes the table of masks as a parameter and returns a boolean for whether the option should be shown.

Fixed modApi:addNewUIScreen

Added new functions for modifying hud elements to modApi: addNewUIScreen, insertUIElement, insertUIElementsAtPath, insertUIElements, modifyUIElement, and modifyUIElements. They unload automatically, so call them in load instead of init.
simdefs.SCREEN_CUSTOMS is now considered legacy code: It remains available but further use is discouraged.

Values for mainframe_iceBonus other than 1 are now supported.

Potential fix for non-steam versions of mod_manager.

Fixed that shop and compiler terminals didn't account for increased program slots when dragging instead of clicking.

On the generation options screen, changing enabled mods no longer resets other mods' options.
Fixed bug that added locked doors to laser panels. (Unverified, if you still get locked doors leading to an empty tile or into lasers, send me the savefile)

Calling pairs on itemdefs will now iterate over it alphabetically, to guarantee consistent order across mod reloads.
To achieve this effect on other tables, add them to the global ALPHABETICAL_PAIRS table.

Fixed crash when more than 12 programs were installed.
Fixed a vanilla bug, where some laser barriers could rarely replace doors with walls, making parts of the level inaccessible.
