changed logfilepatternreceiver parsing to use .*? and .* instead of .+? and .+
allows use of empty string matches - example: when ndc is delimited with brackets but there is no NDC value, [NDC] in the logFormat will match [] as well as [some ndc value]
I don't believe this will break existing users of LogFilePatternReceiver, since folks were unable to match fields with no text (they were required to have at least one character to have a field resolved) and this is still supported.
