Network Rework Updates pt. 2

Updated lobby management, new players now request the roster from the
server to prevent incomplete data.

Update player management, after server creation, the server begins
populating its roster. This is used for storing match-related data,
whereas the lobby managerment script only cares about who the player is
and what team they're on. Stored on server ONLY as all updating and
calculations are handled there.

Created GUIBar for more efficient Health and Mana display and
customization.

Created NewHealth and NewMana, they currently hold only the old Health
and Mana code but will be updated to work with the new GUIBar. (These
exist merely to ensure the game is playable without having to constantly
comment and uncomment different sections of the old scripts.)
