Bukkit

= Main Change =
Fixed most (if not all) database issues.
Please still create a backup of the old variables table just to play it safe.
Part of the fix required to save and load all variables on the main server thread, i.e. performance may suffer.

= Improvements =
Changed the updater to adhere to the new Bukkit guidelines
Improved the automatic config updating
Should be compatible with Java 6 again
Decreased chances of errors due to improved automatic code analysis
Added a workaround to be able to remove a player's tool in a click event
Added workaround to make Skript more compatible with mods that dynamically change enums via reflection. If they do this improperly Skript will still not be compatible with them however.
Added some 1.7 block to the code
Improved/fixed visual effects
Improved expression lists
Added an error on an unsuccessful hook into another plugin
Improved regions support
Added expression 'me' that can only be used in effect commands
Improved documentation generation
Improved effect commands
Added 'luck' and 'lure' enchantments now that Bukkit supports them

= Fixes =
Fixed configs only working with tabs. You can now use any indentation again, and even use different types in one file.
Fixed some other minor config related issues
Fixed error reporting not reporting the whole error
Fixed the pressure plate event to also fire for golden and iron pressure plates
Fixed a few issues with custom language files
Fixed "neither ... nor ..." not working as expected
Fixed some log-related errors and fixed some log messages that didn't appear at all
Fixed not complaining about storing an entity or other non-serialisable data in list variables
Fixed the Bukkit command registration hack to work in 1.7.2 R0.4 as well
Fixed effect command to use english

= Code Related =
Slightly improved directions
Minor performance improvements

Added some more comments to the API
