Team based boost mod

[Al12rs]

Description

Added a new gameMode that allows users to change the max amount of boost players can use. The mod allows team specific settings to allow asymmetrical gameplay (champs vs scrubs).

Changes proposed in this pull request

• Added two new files: BoostMod.cpp, BoostMod.h.
• Changed the solution to handle them.
• Edited RocketPlugin.cpp to include the new gamemode.

Things add later on:

• Allow options per player on each team instead of only teamwide.
• Allow changing boost type (unlimited, recharge etc).
• Possibly other boost related modifiers...

Attention! These changes have been tested in a local lobby by myself since I couldn't get my friends to join. It might be a good idea to test them on a lobby with more players before shipping.

Rewrote it for the next update to get the style more inline with the rest of the project.
