Allow users to set location of .xsession-errors

[spikethehobbitmage]

A more flexible approach to #335 that allows users to set the .xsession-errors path directly. Supports shell expansion in the forms $VAR and ${VAR}.

Someone more experienced with glib should look it over. I'm not certain I've got the pointer semantics right. The GRegex object should probably be static, too.

This seems to have stalled. Is there any way to nudge it on?

I've stalled out. :( If someone else wants it, go ahead. It's a pretty trivial change but it probably needs to be rewritten. I don't claim any rights to it.

Ah, I slipped over your second paragraph in the original post. Unfortunately I am not the one experienced in glib, let's hope somebody with knowledge picks it up.
