Grabber may grab unpredicatable results when a parameter is not found

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Select NFO grabber in Grabber Engine
2. Select an NFO that does not have a <language> tag or a <studio> tag, etc.

What is the expected output? What do you see instead?
Expect output to be blank, but it outputs whole string from start/end parameters

Please use labels and text to provide additional information.

Grabber Engine currently falls back to whole string ("if results = 0 then 
return original string"). Removing this may cause regression in other grabbers.
