[BUG] XP From Gems / OOB Does Not Save Without Finishing Level

As Starmute reminded me, the game currently does not save experience gains from Gems / OOB skills until your client submits an update to the server. This currently only occurs when:

1) You finish a level
2) You complete a Task

I plan on adding a call to submit an experience / level update request when you exit from a level to ensure Gem / OOB / Other Skill-related experience gains are retained, even if you do not complete level(s). This will not fix the issue of experience being lost when the game crashes.

I've added a submit call for player XP when the player quits a level.

I decided not to add a call on restart, because theoretically you could spam Quick Restart and lead to a possible DoS attack on the servers (it's much less likely for someone to spam Disconnect.)

Exiting a level will now submit player experience, regardless of completion status.
