On bug sprint day I decided to go for a tiny little improvement in the GUI 
of pcb: 
In the current release the dialogue File->Preferences->Layers->Groups 
presents the "bottom side" above the "top side".  Turned out,  changing 
the order is a result of the way layers are internally managed in pcb. 
"top side" and "bottom side" are aliases for the two silk layers on top 
and bottom.

The dialogue simply does a for loop over all layers including silk. The 
top silk layer is hard coded to be the last in the layer stack. And bottom 
silk is the last but one. So bottom gets rendered below top. With some 
special casing I was able to swap the order in the display.

While at it, I also touched the way the radio buttons are rendered. Some 
GTK themes like to make hard to spot the difference between pressed and 
default state of radio buttons with text. Unfortunately, this includes 
themes which are installed by major distributions like Ubuntu. 
However, the on-state of radio buttons without text is clearly visible in 
all half way decent GTK theme. So I tried to use this variant. 

See this screen shot before/after for the theme MurrinaCream:

PS: I first tried to attach the screenshot to the mail. Apparently it did
not go through. Probably because of size constrictions. What is the limit?
