Remove inheritance of More action on first action

More indicator in the action dropdown should not inherit the class
of the first action. Any custom behavior attached to the first action
will also be inherited by More.

Example: If the first action had btn-danger, the More button become
red too. This might give the user the impression that More is also
a dangerous operation.

Return an empty string rather than None when calling repr()

Repr() should return "a string containing a printable representation of
an object," which is a convention Sphinx 1.2 relies on when building
the docs.
