OL specific fixes
Fixed bug handling multiple active spell duration requests. Added version number to spells.xml with warning on load if not as expected.  Added #buffd command if durations debug enabled, currently just re-requests durations for active spells.
Added invisibility poisoning to buff count trigger.
Initialise mouse variables.
NULL terminate the dark_channeltext config options which should fix a crash on opening the options window.
Added item description filter within storage category.  Type text, filter items. Non matching items are grayed out.
Fix some of the clang compiler warnings.
Add option to storage title menu, to disable item filter.
