building & cleaning scripts refactored for an understandable output (e.g. in case of error)
build scripts seems work smoothly now :)
introduced grunt fixing #56 from forked repo (the main one). Running tests, sometimes I receive 5 or 6 fails (Dunno why this unregularity) but anyway this behaviour occured also before this commit...
Removed verbose option.

Removed -v/--verbose (new options) to building script during npm install for a less spamming output.
