EPEDEV-357 - CM

EPEDEV-357 - Rearrange template files in modules and theme as
appropriate

1. Added a theme_registry_alter() and insert_after_first_element()
2. Moved the template files to their appropriate modules and removed
from epe_theme.
3. Updated the template files to include the viewpage.tpl.php from the
theme in the same way epe_llb did.
4. Also moved epe_cm_node_edit_form.tpl.php to the templates directory
and updated the hook_theme() to reflect the new path.
