extra '/' in xye level locations

[Bryan Ritter]

In Debian Testing Xye game locations have an extra '/' in the middle
e.g.
/usr/share/xye//levels/tutorials.xye
instead of what it's supposed to be
/usr/share/xye/levels/tutorials.xye

Viewable from the 'Xye - Select a level file' screen -> Location.

This affects how levels progresses are saved
old level progresses that are saved without the extra '/' aren't recognized as
the same level
new level progresses are saved with an extra '/'
This could be corrected in such a way that level progress will be saved
correctly? and if possible, The messed up ones automatically corrected, provided
there's no conflicts(i.e. there's a level where progress is saved with the extra
'/' and without the extra '/'), and if there is conflicts inform the user what
they can do, or something like that.

This didn't occur with Debian Stable. (for me at least)
