Lots of wording improvements for the project settings area

Summary:

 - Mostly very small things involving use of "a", "the" etc.
 - "post-receive" hooks are usually written with the hyphen in the name .
 - I changed the Web Hooks page to have a title consistent with all the other
   pages in the settings area.
 - More consistent usage of full-stops in lists.
