Merge pull request #218 from devton/master

Added a view for projects in home page
commented out rack-mini-profiler, we should use this only when profiling the app, otherwise it keeps getting in the way of browser request logs and consuming developpers time
added by_permalink scope spec
ProjectsController show action cleanup
added not_deleted to by_permalink scope and removed to_param method (it's silly to use this having the permalink)
now we dont redirect to permalink anymore, don't think this behaviour is needed now that everylink to project show uses the permalink.
fixed some links to project that were using the project id instead of the permalink
