added FIXMEs for purge

register template .post script and continue
sort templates before other files, but after .post scripts
call callback on the generated file
if template, generate new file
callback funcions generate templates
pass post_dict to generate_template()
put name._template in the post_dict for template generators

unused var name3
fix wrong variable
return True so that overlay.walk_subtree() will continue
do not ignore templates

This was old code that was in the way
pick correct name for the template
template generators are in post_dict by .template path

The dest_path for a template is actually in the overlay dir
move this code
it's done
