CONVINCING DESCRIPTION

This PR adds a new command to the permissions plugin of the command console. The command "effectiveAuthorisations" allows administrators to check which authorities a particular user has, either globally or in relation to a specific node. The latter variant of this command allows for better analysis of potential permission issues, as the check will include dynamic authorities that may affect the user on node in question, and essentially gives a low-level list of authorities which will be considered by Alfresco during ACL checks.

If popAuth() throws in 115 above deep in the implementation, you could end up trying to popAuth() again. Seems very unlikely, maybe it would be better to move the popAuth into a finally()?

Unfortunately, there is no finally supported in the Rhino version used in Alfresco, AFAIK. At least I once tried to use it and failed, so I adopted that pattern.

Created #169 to track that.

Weird, I though I used that inside JS Console a couple of times before !

@yregaieg Yeah, we were talking during the hackathon Zoom session and I am fully prepared to consider that my state of knowledge on that might be seriously outdated because I never tried again. Don't want to change that on a whim here though and thus created that #169 to do a proper verification.
