All commands are single-words again: /tc shops, is now /tcshops. I did like the old way a bit more. But that doesn't really work with how the config file and the 'usage' attributes work. The currency and shop commands are split up also, see the commands list. The canplayer command is changed to tcplayerperms.
Added optional logging of all shop interactions ("log-shop-use") disabled by default.
Added property to use a stack size limit of 64 instead of the normal behavior ("normal-stack-size") defaults to the normal behavior.
Support for Bukkit's built-in permission system (with preset op/anyone permissions). This is used when the Permissions plugin is not detected. Since the default configuration defaults to logic permissions for op/normal users, you do not really have to use any custom permission settings or plugin.
Added two language lines: SOLD_X_A_FOR_Y_B, BOUGHT_X_A_FOR_Y_B which are shorter variants of the already existing YOU_* entries. These are used for the optional shop use logs.
