Added mulesoft repositories to pom.xml to solve the problem of not findi...

For a particular combination on the way repositories are set, if not information about MuleSoft repositories, it was impossible to package the project even having raml-parser installed locally.
It's temporarily solved by adding the repos to the pom.xml (I'll make another pull request once this configuration is no longer needed).
It would be good to be in contact anyway. Please feel free to contact me to norberto.herz@mulesoft.com or skype: norberto.herz (I would like to provide some feedback too while I move forward trying out this tool)
