Bard instrument mods should be more consistent with live

Changes:
	Mods are now saved for in the DB so they are loaded on zone
	This allows long duration buffs from bards that get mods to keep their mods
	Ex. Selo's, Symphony of Battle

	Instrument mods are applied to basically anything that is an instrument skill
	The only exception to this is discs (ex. Puretone is Singing but always 10)

	Singing spells from procs (Ex. Storm Blade) that are instrument skills should
	inherit their buffs instrument mod. Doom effects should also. This isn't
	implemented yet.
