Initial attempt at cleaning up the API

Context.object accepts a template or a string name (and now a type
flag).  Module.object only accepts a string (because a template already
has most of the stuff built in and might as well be passed to the
Context.object constructor).

The gotcha here is the absolute flag, which must now be set
appropriately in all cases *except* where the module is constructed
with an offset of 0 (whereby it will have no impact).
