EDGE implementation

1) Add an edge.sh file; EDGE variable can be a version in XX.X format,
a revision in XXXX format or otherwise will checkout the trunk.

2) Dumped the nzbget.conf template. firstrun.sh will now use the
default template from /usr/share/nzbget/webui and apply the necessary
changes inline.

3) Some cleanup in Ubuntu repositories.
Some additions
