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'
