Download Manager

This version now sets the window icon in gdownman,
uses a progress bar for % done, saves column width
between sessions, and uses the same width of columns
for all the projects.

Gdownman will now autostart the daemon if needed. You can change the speedlimit of a download while downloading, and some bugs were fixed.

Selecting a different target directory from
project's default now works. Glade files are now
installed, so you can now select File->New Url
and Project->New Project without it crashing.
