feature assignment can now be done when creating a feature
some UI cleanup
problems now honor role (PM vs USER) and only show the necessary fields; refactored feature select2 options to global function
basic roles & permissions working. this is just a UI/presentation protection, not a full-blown security implementation so it could easily be hacked (if we cared, which we don't)
show state in list of problems where appropriate
oops, shouldn't have checked this in
a little better browser compatibility
get rid of the footer (it's kind of useless) and make the header a normal element rather than a fixed position item that makes iOS weird
