Core/Misc:

* Fix some codestyle, fix some typos

* Change CMakeLists for: Custom (can be uncommented), Events, World
** Custom is theoretically unchanged. You can, however, uncomment the glob_recurse that initializes every file within. This might be easier for beginners.

* Introducing the IP Based Action Log System:
** On several different actions, e.g. Login, Character Login, etc., a new entry is added
** Can be logged on and off in worldserver config
*** Disabled by default to prevent increased log db size for unknowing users.

* Add a new row to account table called 'last_attempt_ip'
** Lists the last ip trying to connect to the account

* Add a new type of HookScripts: AccountScript
** Includes: OnAccountLogin, OnFailedAccountLogin, OnEmailChange, OnFailedChange, OnPasswordChange, OnFailedPasswordChange

* Added new Hook to PlayerScripts: OnFailedPlayerDelete

* Added new variables to PlayerScripts: OnPlayerDelete
