Massive overhaul of "generate project" feature

previous incarnation was woefully lacking.  new feature is much more
extensible.  still need to remove old POS integration specifics in
some places.

and a couple of unrelated things that snuck in..

- deprecate `rattail.util.OrderedDict`
- deprecate `rattail.util.import_module_path()`
- deprecate `rattail.util.import_reload()`
