#530 [Advanced compiler options dialog/regex tester] Add name of matching regex to test result window

[Jannick]

Advanced compiler options dialog - Settings > Compiler > (select compiler >) tab 'Other settings' > btn 'Advanced options' > tab 'Output Parsing':

When testing a line against the list of regular expressions of the selected compiler, it would be great to have in the test result window the name of the regular expression matching the test string (which is first in the list).

Purpose - better analysis of test results in designing additional regular expressions, since - as pointed out in the dialog box - the regex order does matter.

Potential implementation (but I am certainly in deep water here) - Pass the index - or name - of the matching regex from Compiler::CheckForWarningsAndErrors (compiler.cpp) back to AdvancedCompilerOptionsDlg::OnRegexTest (advancedcompileroptionsdlg.cpp) upon test.
