remove simple-open-loop-policy, it is a bad example, and has an unavailable dependency; and notes on disabling maven incremental build
Create backup of persistent stores at key times

Created on master promotion (technically just before persistence starts) by reading from the store,
and on demotion by HA subsystem by reading from local in-memory model.

Includes new BrooklynServerPaths cleaning up logic from BrooklynServerConfig, and some cleanups to the utils in BrooklynPersistenceUtils.
Relevant config keys are the *PERSISTENCE*BACKUP* options in BrooklynServerConfig.

Logging now looks like this:

In future it would be nice to have periodic backups and some automatic clean-out support ... but for another day!
misc doc fixes and code comments/reporting

including improving persistence docs, and comments on tomcat and typo in couchbase
fix bug where getMembers() used by the GUI was disallowed for entities in hot standby
fix JS GUI server time race (rendering)

fixes a bug where a server with clock a few seconds ahead of local causes weird message "in a few seconds" and possible flapping with "a few seconds ago"; just backdate it to be a few seconds ago if delta < 10s, else say "server clock in future by a few seconds" (or other time if it's really out of sync)
track soft references (esp script output) and report reclaimable memory as part of brooklyn-gc reporting
remove pom instructions generating index.list file

removing because it is including dependencies meant only for a shaded jar, which causes other tools to assume other jars do NOT provide certain packages; can manifest as guava not being found by osgi when constructing boot classpath; have confirmed JMX agent works without it (and the other jmx agent did not have it)
additional m2e excludes for 4.4
fix mis-attribution in notice, and other tidies there (punctuation mainly)
Merge branch 'persistence-can-export-and-more' into misc
