A lot of changes to get the skill users request spec working

The application controller gained some white space.
teh skill users controller gained a current resource method
the skills controller shoudl be unchanged. Whitespace if anything.
The user controller gained an index method.
application.html.haml gained a home button
skill users views all got modification to show data correctly. the _form file got a drop down list of skills instead of a text box.
Currently the form pulls current user from the session. It should be pulling it off of the user that was clicked from the index.
the skill user spec was corrected to actually represent the content of the form.
