Should be able to add inline comments to ignore line

[shakedlokits]

As of now, the only method to manage rules in sonar for the ruby plug-in is by macro managing the rules through the QualityProfile[1] system, lacking the ability to ignore specific lines using in-line comments similar to the Java plug-in.[2][3]
I believe it is a valuable feature to be able to micro-manage our rules.
