Room class seperation

[wxyz-abcd]

We need to seperate Room class into two different classes: HostRoom and ClientRoom. Room class will become the base class for these subclasses. This is necessary to make writing code easier for people, and writing documentation easier for us.

This has to be done after getting rid of the roomObj hook.

This is a must have, for sure. Aren't RoomHost and RoomClient names would be better?

Names don't really matter that much. :) After almost 3 months, this issue is still open... The main features are still not completely finished, so I cannot focus on these smaller issues. :)
