Create an m1 plugin that will add/update m1 projects in Continuum

Trygve and I chatted and figured that this approach might be easier then trying to pull in all the m1 code to read m1 POMs inside Continuum. The m1 Continuum plugin could read all the necessary project information (taking into account, property interpolation and entities) and submit it to a Continuum instance using the SOAP interface.
