    adium themes: crash less hard when Template.html is missing
    
    If Template.html is missing, then you haven't installed Empathy properly
    (or set EMPATHY_SRCDIR or whatever in my case). But previously we would
    just crash later down this function when passing template_html to
    string_with_format() without checking if it's NULL. This patch makes
    it fail a little less inscrutably.
