The admin templates are kind of annoying in that if the object doesn't exist

yet, they don't include the object-tools-items block. This meant that the "Show

SSH Public Key" link wasn't shown for the "Add Repository" form.
This change overrides the object-tools block (instead of object-tools-items) to

unconditionally include the <ul>.

Looked at both the "Add Repository" and "Change Repository" forms. Saw that the

SSH key link was present and functional for both.
