HTM::Template::Default radical update
Made a pretty radical update to Html::Template::Default.
This module allows you to specify a default HTML::Template source, for example one that is hardcoded. And also to provide a filename source. And if it finds the filename source on disk, it uses that, if not, it uses the template source you hard coded or opened from elsewhere.
The new interface is exactly the same as HTML::Template, the only difference is that you can provide a filename source in addition to one of the sources; scalarref, arrayref, or filehandle.
