add initial version of maven (goalhub) helper project , that currently
does the following (working, though not extensively tested yet):
1) toggle between development/production mode; the snapshot flags will
be automatically added/removed based on this
2) git pull projects and automatically detect if we are in a correct
branch (master or other development) depending on the mode
3) toggle between install/deploy mode (the eventual action);
dependencies will be automatically updated
4) integrated dependency model (e.g. wanting to build messaging will
also want to build runtime automatically)
5) version update system (major/minor/build) that handles dependencies
