Changes to Voting procedure.

The purpose of this proposal is to update and clarify the voting procedures of the House.

The proposal attempts to accomplish the following tasks:
* Adds common procedures already in use like white-balloting and automatic tabling.
* Adds objections to ensure that no-one can prematurely end debate.
* Adds force-* motions to counteract the potential for frivolous use of objections.
* Tweaks the README to clarify that changes should not be made without House approval.
