#9 Broker should not abort

[Igor Nekrestyanov]

If no collections are present in config file
then broker will abort. As a result user
sees internal server error page - this is BAD.

It seems better to simply report on such errors to
log and present empty result page.

I suspect there are other places in broker
which may trigger explicit abort.
They should be eliminated.
(Note, there is similar task for common components)

this is important usability issue.
