Add myself to DOAP file

So I can do the release next.
build: don't generate modules.gresource.xml

Doing so breaks distcheck, because it tries to write to $(srcdir).
Instead, always include the Gtk override in the modules, but
make it do nothing if gtk is not enabled.
jsunit: prepend the srcdir when looking for uninstalled files

Fixes distcheck
Fix distcheck

By removing a lot of generated files on make clean
Release 1.39.91
