Group support
Add support to create groups, join them, post to them, leave them, delete them, etc.
There is WIP support for all this, but there are a few features missing (like nicely listing groups you've joined) due to functionality missing in the Pump.io core.
You can test this by running qmake with DEFINES+=GROUPSUPPORT, but make sure you use "make clean" first.
***This is pretty ugly and should never be enabled when building Dianara for end users.
