Item2188: Bad query makes DBRECURSE die ungracefully

I use some parameters to an %INCLUDE% to set variables in the filter when working with %DBRECURSE%.

For example:

%DBRECURSE{"%sometopic%"
  filter="%somefield%=~'SomeTopic'"
  format="..."
}%

This dies ungracefully with

Foswiki has encountered an internal error... ERROR: can't parse query "%somefield%=~'SomeTopic'...

Attached a diff which I think solves the problem.

Also added & documented a warn param (defaults to 'on') to mimic DBCALL's warn param. Also documented existence of warn param for ATTACHMENTS handler.

I will commit this once I've tested the new warnings being triggered during recursion, as I've made some assumptions there I need to verify.
