Requiring minimum client revisions

Helix server offers a mechanism to control which revisions of client applications are able to connect to it.

To require a minimum revision, set the configurables minClient to the appropriate revision, and (optionally) set minClientMessage to the error message displayed when users of older applications connect to the server.

For example:

$ p4 configure set minClient=2010.2
$ p4 configure set minClientMessage="Please upgrade to 2010.2 or higher"
