gtk-reftest: Allow loading code for reftests
When connecting signal names, gtk-reftest now allows you to use a colon in the signal handler name like so: module:function_name where module is a module loaded from the same directory (or the .libs subdirectory for compatibility with uninstalled libtool) as the running test and the function is resolved in that module. Of course, normal function names work as before.
