Break Previous Cursor Definitions

A collection of breaking changes from 0.C to 0.D regarding cursors:
The cursor definitions [SuperWeapon]Cursor and NoCursor no longer read the seven separate tags. All now take a single cursor name from the new [MouseCursors] list. Modders will have to convert their cursors to this new format. The default cursors have been updated to refer to existing cursors: Cursor defaults to Attack, NoCursor defaults to Disallowed.

The global tags EngineerDamageCursor, TogglePowerCursor, TogglePowerNoCursor, InfantryHealCursor, and UnitRepairCursor have been removed. Instead, there are new named cursors in the [MouseCursors] list called EngineerDamage, TogglePower, NoTogglePower, InfantryHeal, and UnitRepair respectively. Those cursors can be overwritten. No functionality is lost.
