cleaned up Gemfile

Refactoring for B#1126 fix. Photo model is now fatter with #destroy logic while Photo controller is thinner.

added vendor/cache to gitignore file

removes underline in tag search form on getting started page

dispatcher

move _donate.html.erb to _donate.html.haml and make it translateable

rescue unmeaningful exception from settingslogic if the namespace doesn't exists and replace it with meaningful error message

So the cucumber step 'And I follow "link title"' does substring matching, and will click on the first link it finds that contains "link title". Thus if you have 2 aspects, one called PostingTo and the other called NotPostingTo, doing 'And I follow "PostingTo"' may click a different link depending on what order the aspect links are in.
ka-sigh.
