gitolite_info func moved to DDR.dvcs module; now takes argument
report bad RSA key; add TODO

The storage checker function would fail if the server user's

alert the user to that fact.  Add error message.

Note that function will report as unreadable if there are no
collections for the repo/org combination.
don't log quite so much
