Start using VM API version

Not maintaining backward compatibility yet, but lets start to
keep track of API break so we can error if unsupported.

Add API name.
Allow server to create cvars on client again

If connecting to server with different fs_game, might not of registered the cvars in cgame yet
(so create it so cgame can get the value).

Don't mark server created cvars as read-only (they'll be stuck that way), but still don't let user change them.
Change order of refusing to set cvar so we tell user cvar is server created before read-only etc.
