Improve Regex support for groups in Start/End Parameter in Grabber Editor (e.g. #REGEXGROUP#)

What area does your enhancement or feature relate to? (i.e. Config/Setup,
GUI, options, Skin, AMC Updater, Grabber Interface, etc.)
Grabber Editor
What is the purpose or benefit of the new feature or enhancement?
In some cases/fields the Grabber must search almost the whole file to match 
RegEx groups, or you need to use the 'Countries' parameter to match results. 
When grabbing from sources with minor variations in data format, this means you 
either need a separate grabber for each variation/source, or use complex regex 
and mapping which can reduce performance.
How would you expect it to work? (Accessed via, new settings required, Skin
changes/new properties)
Add a #REGEXGROUP# to Start/End parameter to simplify the limit of certain area 
selection for the inner grouping/matching.
Can you illustrate it with examples such
as images (screenshots), scenarios or examples from other Plugins?
In the case of NFO grabber, for several person fields like Director, Writer, 
you must use <movie as start and </movie as end since you never know what 
order, the fields/tags may use and you want to grab all cases of 
<director>(?<person>.*?)</director> RegExp
