Changes since release 0.2

* More informative error messages

Many of the errors that guile-xlib can signal now produce more
information messages.  For example, the error that is signalled if you
attempt to map a third party window now includes a description of the
bad window argument:

guile> (define r (x-root-window d))
guile> (x-map-window! r)
ERROR: In procedure x-map-window!:
ERROR: Window #<x-window 80c5878 XID 25 third party> belongs to a third party
ABORT: (misc-error)
