[documentation] New Drupal project component: Documentation

[Angela Byron]

Thanks to Jim Li's suggestion, I've added a new "documentation"  
component to the Drupal project:
http://drupal.org/project/issues? 
projects=3060&components=documentation&states=1,16,8,13,14,15,2,4

I've tagged a couple issues with 'documentation' that I knew about.  
Please feel free to tag others, and if you find any bugs with core  
help text or any of the .txt files that ship with it, etc. :)

And remember: RC1 is string freeze!
