Make the rule File Content Regex print the offending lines

[acecilia]

At the moment the printed errors are not very informative, and is impossible to find the offending line. For example:

/../../../ExampleApp/ExampleApp/Resources/en.lproj/Localizable.strings:-1: ProjLint:  File Content Regex Violation – Content matched regex 'Regex<"\n"(?!((([A-Z][a-z ]*)" = "\3")|(L\.[a-z][a-zA-Z]+" = ".+"));)">' where it shouldn't.

It will be very helpful if the error shows the offending line.

This issue seems to be also related to #29
