[Sergey Starosek]

As requested in http://trac.hohndel.org/ticket/563 here is a set of patches
that implements proxy support in Subsurface. Please review and let me know
if these are correct.

Also look at patch #5 as there're several open questions.

P.S. Some new icon is required for "Network" page under Preferences.
