Instead of having the template files and images in /usr/share/znc/www/<mod>/,
modules now get to use /usr/share/znc/<mod>/tmpl/ and files/ for this purpose.
This puts those directories for static data to good use again and might even fix
some bugs (after all, the code for that dir is older and more tested than the
new code for www/).
