Little Gruntfile cleanup (comments + the deprecated 'server' task)
Added a "lock registrations" button to the tournament admin page
Got rid of the GA boilerplate we're not going to use (at least not right now)
Reorganized test directories a bit to accommodate for new tests.
Added a utils script built as a module in order to help unit testing front scripts (generates a console error @runtime right now but it seems to work fine otherwise)
Updated Gruntfile to take new a unit test directory into account
