[Bug-gnubg] saving board designs

[Joern Thyssen]

Hi all,

I'm wondering how to implement the saving of board designs. 

Currently, the board designs are defined in
PKGDATADIR/boards/boards.xml, but on multi-user systems this file is
most likely not world writable. 

Do we write a new file $HOME/.gnubg/boards.xml [*] with the user defined
boards?

[*] I suggest we make a settings directory .gnubg to hold gnubg files,
since we have quite a few.
