Installation scripts for daemon mode on Ubuntu using Upstart

This work is based upon upstream work in bitcoin core on the master branch and in some PRs.
The "Cherry Pick" commit is here: https://github.com/msgilligan/mastercore/commit/55a97b93223919171195fb11c11281c9cdb0be3e

All files (both the "cherry pick" files and the ones that I've added are in the `contrib` subdirectory.


I'm not in contact with @m21, but I think this was no manual close, but related to the 0.0.7 release and the branch restructure - mastercoin-MSC:michael-0921 was deleted and I assume this disconnects associated PRs?

The new dev branch is https://github.com/mastercoin-MSC/mastercore/tree/0.0.8 and you might keep an eye on https://github.com/mastercoin-MSC/mastercore/issues/130 where I suggested to use a more telling branch/release name - just for the case 0.0.8 will be deleted as well.
