[katello-devel] Katello UI - view helper for adding tabindex

[Brad Buckingham]

Added a very simple helper called 'auto_tab_index' to the 
application_helper.rb to facilitate adding an HTML tabindex attribute to 
pages in Katello.   This helper should work for most of our views that 
have a sequential flow.  So, rather than manually assign a number for 
tabindex, call the view helper auto_tab_index and let it assign a value 
for you.   The benefit of this approach is that we can easily add new 
fields to a form without accidentally affecting the tabbing behavior, if 
we were to forget to update the index :).
