Installation scripts for daemon mode on Ubuntu using Upstart (resubmission)

[msgilligan]

Contains configuration files and an installation script for setting up Master Core (bitcoind) in daemon mode on Ubuntu using the Upstart init daemon. This is part of the work necessary to implement Issue #131, but does not address the actual packaging.

Some of the files are from the current upstream master branch. The files in contrib/msc-ubuntu were created specifically for Master Core (a README and a default bitcoin.conf file for Master Core)

Here are some of the merged upstream PR's included in this "back-port" to Master Core.

• bitcoin #4611
• bitcoin #4577

Upstream issues:

• bitcoin #4124

Note: This is a resubmitted PR, the original PR was #129. This PR is now based off of the mscore-0.0.8 branch and includes a change suggested by @dexX7.

@m21 @zathras-crypto: this was resubmitted and adjusted a few times to catch up, so I think this should be looked at rather sooner than later.

@msgilligan: is there anything you'd like me to test, so I can confirm correct behavior?

[msgilligan]

@dexX7 You could test the install procedure that's documented in contrib/msc-ubuntu/README.md. You could then verify that bitcoind starts up on OS reboot and that you can kill bitcoind and it will restart.

One issue with the installation script as it stands now is that it is not intended to be an update script that will add init support to existing installations. @achamely brought that to my attention yesterday.

These scripts will need to be changed now that the binaries are named mastercored and mastercore-cli.

And we should also decide if we want to use the bitcoin user:group and all the same directory and file names as Bitcoin uses. I suppose that as long as our code defaults to using the *bitcon* names our installation scripts/package should probably do the same.

These should be changed to reflect omni
