Convert pom.xml from dos to unix.
Update dependencies and fix build

- 0.6.0 rc2
- Match Brooklyn's jclouds and testng versions.
- Fix build by removing erroneous @Override
Use logback-custom.xml in src/main/resources

Move custom logback.xml to assembly
Various fixes

- Add dependency on brooklyn-networking and Brooklyn 0.7.0 snapshot
- Fail install if init-brooklyn-db.sh script fails
- Unset JAVA_HOME when running install
- Fix pid file location for shutdown
- Disconnect Postgres on stop, just to be sure

Last two should ensure clean shutdown in normal cases.
Move OpenGamma applications to app package

- Rename OpenGammaCluster to ElasticOpenGammaApplication.
- Move cluster factory creation to OpenGammaClusterFactory class
Adds CloudStackOpenGammaApplication

Runs OpenGamma behind a subnet and uses CloudStack's load balancer
rather than Nginx.
Expose ConfigKey for initial server properties file

Defaults to classpath:/io...brooklyn.properties.

Also adds a document explaining the configuration files included with
Brooklyn and how they have been modified from the OpenGamma example set.
Document CloudStackOpenGammaApplication and remove default location.

Also formats config readme to be readable.
Merge remote-tracking branch 'origin/cloudstack-app' into cloudstack-app-2

Conflicts:
	pom.xml
	src/main/java/io/cloudsoft/opengamma/app/ElasticOpenGammaApplication.java
	src/main/java/io/cloudsoft/opengamma/server/OpenGammaServerSshDriver.java

All trivial conflicts, fixed
use newer networking project (where LegacySubnetTier exists)
name the init-db script better (for when exploring the tasks)
