Added option com.openexchange.caching.jcs.remoteInvalidationFor PersonalFolders to file 'cache.properties' to enable/disable invalidate events for non-global folders.

That option specifies if changes to personal folders (personal in terms of non-global e.g. folders kept in database) are supposed to be propagated to remote nodes. This option is only useful for installations that do offer collaboration features or do not support session stickyness.
For instance users are able to share mail folders or might be load-balanced to other nodes while active in a single session.

Default is 'false'
