Made some format changes. Added new rule to requests and ideas.

Proposing a new rule to the Requests and Ideas section. This rule will require posts in the Request/Ideas section to actually contain the idea for the mod. Posts saying "I have an idea and I want someone to code it for me, pm me and I will then tell you what the idea is" seems like it would be better suited for a "team" request. 

I also fixed the wording of the "no picks, no clicks" and added a few periods.
