Rule Updates

[Tripper]

We've updated the rules a little, don't worry though - only minor changes, nothing too draconian (yet ).

The Rules - these apply across the whole forum.
The Signature Rules - these are limited to signatures, which members can have at the bottom of their post.

A run down of the changes:
-Signature rules reorganized to make clearer, the size limits have been increased and we've also made clear the limits on text signatures.
-Added rule #5 to the general rules, this is about advertising on the forum which isn't allowed except in two designated places (signatures, profiles) where it must be of a suitable nature.

Thanks for reading!.
