[HOT] Tasking Manager server changes

[Dražen Odobašić]

Hi all,

we have moved the Tasking Manager (http://tasks.hotosm.org) to the server with
more resources.

We also changed the hosting environment, previously it was apache2+mod_wsgi, and
currently we are running on nginx+uwsgi. The hosting environment should not
really affect anything, however, if you have some time please click around, and
test.

Thank you,

Dražen
