More work on ability system

* Renamed Untitled Triggers to proper names (Restart Game,
OnPlayerLevelUp)
[NOTE] Chris, perhaps change CatalogMethod in OnPlayerLevelUp to
UnitPropertySet instead? Not sure what kind of overhead CatalogMethods
have, also AFAIK they aren't applied to each active instance of that
unit type so what you're doing right now shouldn't have any effect.
* Ability Table - Indexes of Unit Custom Values simplified slightly
+ NEUTRAL_OWNER constant
* Ability Table - Indexes of Unit Custom Values renamed to Ability Table
- Indexes of Unit Abilities (Player)
+ Award Ability fully implemented but unsure if it will work or not..
Needs thorough testing
* OnPlayerLevelUp will now also call Award Ability
* Disabled Debug method "Ability Data of Unit"
+ "Print Unit Ability Raffle Data" debug command added
