Add 'My' > 'Groups' menu entry that shows list of own groups

Users can already see a list of the groups in which they are member
under 'Settings' > 'Groups', but most users don't know about this.
They rather expect this to be available from the top menu.

Putting this under 'My' > 'Groups' and not under 'People' > 'My
Groups' has the advantage that the menu entry is then configurable
and users that don't need it, can remove it.

The my groups screen is displayed for '#/groups/self'. There is no
'admin' prefix as we have it for the group list screen
('#/admin/groups/') since this prefix only exists due to historic
reasons and should rather be removed. '#/groups/self' was chosen to
make the URL similar to the URL of the user dashboard, which is
'#/dashboard/self'. At the moment only '#/groups/self' is supported,
but in future this may be extended to also support
'#/groups/<account-id>'.
