ROBODoc robodoc

Got rid of a compiler warning

Added hint for including external DOT files

Bugfix: Calling External Tools did not work well with multi level source directories. The inclusion of a DOT file was only possible if it remained in the current runtime directory.

Removes DocX directories (they should be created by robodoc)

Added tests for the option --source_line_numbers

Increased column number to 45

Was missing for acceptance tests...

Fixed error in regexp

fixed test rule: underscores in labels are OK

Fixed --cmode test
