Version 1.58

• Better handling of bad Forge Ore Dictionary entries for item tree.
• Silenced some debug output that appeared to be an error.
• Added keybinding config to default Minecraft keybinding options.
• Various enhancements to the API for other mods.
• Configuration screen can now be accessed from the mod list on the main menu screen.
• Sort-on-pickup should work in single-player again. (MP/Server support is more complicated)
• Shortcuts using shift should now work correctly.
• The F3+H display has an added line showing the string ID of items, like Mojang added to the 1.8 snapshots.
• Auotrefill and sort-on-pickup now immediately resync the inventory with the server.

Version 1.57

• Updated to MC 1.7.2 (With many internal changes to support the update)
• Use ID names, instead on numerical IDs for blocks/items in config files.
• Messages during the loading process will now display as chat messages the first time you load a game.
• Rule-based sorting should no longer freeze the game in specific situations.
• Using IDs in custom rules may or may not work.

Version 1.55

• Sort-on-pickup attempts no longer spam chat messages by repeatedly failing.
• Auto-refill will now match metadata exactly on items with subtypes (wool, carpet, stained clay, etc.)
• Major API update, to allow for mods that change the basic player inventory to add compatibility via API.
• Sorting shortcut automatically disables itself when any standard text field is focused. (Ex: Anvil rename field)
• Modded containers will never attempt to 'guess' where the main player inventory slots are. Ask the developer of the mod to use the API for compatibility issues.
• Basic compatibility information can be added to a new configuration file 'InvTweaksCompatibility.xml'. (For modpack builders, this is not a substitute for using the API and will only work correctly for fixed-size chest-like containers)
• Language files are now loaded using MC1.6's resource pack system, so they can be overriden or new languages added by resource packs.
• The override button texture file should now be located at 'assets/inventorytweaks/textures/gui/button10px.png'

1.54b: Extract creative survival tab size to a constant.

More galacticraft stuff, this time for that mod to hook into and edit.
