Conflicts:

Modified the Open-Transactions build to make it possible to build a version
of otserver that can run as a background daemon process. Also updated
docs/INSTALL-Debian_Ubuntu.txt to describe what you need to do to run
otserver as a background daemon. The procedure to run otserver as a daemon
process should be similar on other unix distros.
Merge branch 'otserverDaemon' of https://github.com/monetas/Open-Transactions into otserverDaemon
Updated the build scripts to fully support KEYRING_FLATFILE when building
otserver as a daemon process and removed all hardcoded #define OT_KEYRING_FLATFILE definitions from the source.
