Template Toolkit OPAC

See Template Toolkit OPAC release notes at
http://evergreen-ils.org/dokuwiki/doku.php?id=dev:opac:template-toolkit:release_notes

Additional non-tpac-specific changes include moving web templates
from the web dir into Open-ILS/src/templates/, removing /default/
from the template paths, and porting vandelay strings from the DTD
into the template (for better/consistent translation support).
