Currently, the text-finder plugin enables the administrator to specify a
location to search (file patterns and/or console output), a regex, and a result
(which can be either unstable or failed).

A useful and natural enhancement would be to allow multiple search criteria to
be specified. Each search would consist of:
(a) where to search - files and/or console; OR previous search's specification
(b) regex to search for - OR previous search's specification
(c) what to do if the regex is found - unstable/fail/success

The searches should be carried out in the order listed, and halt at the first
search for which the regex passes, marking the build unstable/fail/success as
specified.

Of course, there can be some optimisations - if two searches specify the same
"where to search", it can be done in one pass.
