PROV-1043 CLI tool to update the installation profile

See http://clangers.collectiveaccess.org/jira/browse/PROV-1043

Adds a caUtils update-installation-profile command

* Uses existing installer codebase with checks that update existing profile items where they match on code/idno/type
* I have added an Updater.php under install/inc that overrides the installer for special cases.
