[X2Go-Dev] Bug#642: I applied the 3 patches

[Michael DePaulo]

Sorry for not replying earlier. Something major came up in my personal life.

Anyway, I reviewed the 3 patches and did some basic regression testing
with the current minGW 4.8.2 + Qt 4.8.6 build configuration. Those
tests passed, so I commit the 3 patches.

Before I update the changelog and mark this bug as closed, I will test
out building with VS 2010 express.
