Big Boost/Earn Meter Fixes!

* Only set the boost from persistence once, allowing for the boost to be changed mid game by other scripts.
* Added `PlayerEarnMeter_SetBoostByRef(string boostRef)` to simplify setting boosts.
* Boosts now correctly disappear after being reward to the player.
* Client-side reward icon will now update when the boost is changed.
* Titan cores will now pull the HUD icon from the core, instead of the titan chassis. Allowing this to be handled better by other scripts.
* Player boost inventory implemented! Now players will be able to store multiple boosts like vanilla.
* Boost inventory limits, all vanilla boost limits are respected, and `BurnMeter_SetBoostLimit( string burnRef, int limit )` was added to accommodate this.
* Fixed the unused nuke titan boost code so that if anyone decides to use it it's not horribly error prone.
