fix populate repo_browser and file_manager bug
Fix for issue 1301: Addedinstance method now() to the flash statement, making it unavailable to the next action.
Fixed a syntax issue in _assignments_dropdown_menu.html.erb view that caused assignments pages to not load.
Changed controller.action_name to target_action, so repo browser actually works.
fix rake markus:reset (wrong namespacing)
fix pdf stalling bug
WOOPS SORRY THAT WASNT SPANISH LOL
change to use def change instead of self.up and self.down
clean pdf stalling fix and finish up
Merge branch 'pdf_stalling_fix' of github.com:oneohtrix/Markus into pdf_stalling_fix
