Bug2152

This is Bug 2153 ( http://bugs.dwscoalition.org/show_bug.cgi?id=2152 )

I submitted a patch for this some time ago (May!) and fu suggested integrating it with the new post page.  This pull request includes the original patch for multiple stickies (to be operated from Display in manage settings) but also a module for the post and edit entry forms which allows the entry to be allocated to one of the sticky positions available to the user.
