Editlock buttons have already been removed; most of this code is
unreachable/useless anyways.
Don't listen to editlock messages anymore, and always set the map
permission to edit unless specified.

Don't include each third party script in a separate <script> tag,
rather have one single main.js file require'ing these different
scripts. Then `browserify' on main.js which bundles everything
into a single bundle.js containing all of the dependencies.
Also add these 3rd party scripts such as jquery, jquery-ui,
select2 etc. using npm, rather than manually downloading their
files from the internet. This should ease the process of managing
these front-end dependencies; upgrade process should be very easy
now.
