Automatically provide 'name' to project templates

Provide the short name of a project (anything after the last '/') to
project templates as the variable 'name'.  If 'openstack/nova' invoked
a template, the variable 'name' would automatically be set to 'nova'
within the template.

Ideally this means that most template invocations in OpenStack's layout
will not need any variables defined.
