Modify PresentsClient and ClientResolver creation so that we can inject

dependencies into both. Moved the legacy statics into CrowdServer so that at
least Presents can be pure (we should probably eventually move them into
BangServer and PiracyServer and fix everything else). Added some useful manager
references to PlaceManager delegate (_omgr, _invmgr) that handle the majority
of their service needs.
