src/features: updated errorRegex to work on Windows

The previous revision to errorRegex removed support for \r\n line endings. This change uses \s* to match all whitespace between the lines in the error message which shoul eliminate this problem in the future. Also, the previous version only allowed uppercase drive letters and my system reported lowercase (ie. c:\) which caused the matching to fail.
