- use gtk_clist_set_column_title to set clist column titles
when possible so that they get the alignment of the column.
- Backport code that cleans up widget hash table in the
GladeXML object on widget destruction. This means that
glade_xml_get_widget() should always return a valid widget
or NULL.
- Move headers to a a libglade-1.0/ subdirectory. This is to
allow parallel installation of stable and development
versions of libglade. Libraries depending on libglade will
probably need to be rebuilt so that their *-config scripts
contain the correct CPP flags.
- update shared library number
