Added support for build_style=perl_module. That means that perl modules

now work on pkgfs.

While doing this work I added some new variables that can be used in
templates:

run_stuff_before="<stage>"
run_stuff_after="<stage>"
run_stuff_before_<stage>_file
run_stuff_after_<stage>_file

These can be used in a template when you need to do some stuff before
or after the stage specified, and the file will be read and the commands
on it executed.

Now that finally perl modules work, add the following templates:

intltool-0.40.4 and perl-XML-Parser-2.36.

Also mktmpl.sh has been updated to understand build_style=perl_module.

ENJOY!
