Cleanup gemspec

* Do not use array for a single item
* Specify license type
* Specify platform (default)
* Provide rdoc settings
Use RubyBBCode as module name

Same as the rest of the code uses
Fix rdoc generation
Remove deprecated method
Start method names in String class with 'bbcode'

This makes it (more) clear where the method comes from.
Any of our public methods (outside RubyBBCode namespace) should start with bbcode for this reason
