#96 xmms window resize/repositionning

[Kyoshiro]

I use kahakai 0.5.1 (btw, thanks for the work ;)

I've noticed problems using xmms :
- sometimes my playlist window locks itself in a reduced size and
I'm neither able to change size with the right bottom resizing button
nor with the kahakai resizing (ALT+right clic). I have to clsoe
playlist, reopen it, and resize with ALT+right clic.

- when I double click on main xmms window, it should reduce into
a tiny bar and grab the attached windows (playlist, equalizer,....) to
make the main xmms window staying where it was. In fact it
reduces but the playlist don't move up and the main window's top
point moves down. (I don't know if my explanation is clear :p)
