- Merged vc.init_motion_ivars into vc.init_state_ivars.
Simplified dispatchers before documenting them ;-)
1.  Merged vc.init_motion_ivars into vc.init_state_ivars.
2. vc.accept_or_done now just calls vc.done:
- This prepares to change all calls to vc.accept_or_done to vc.done. I'll actually do this after more testing.
- To do this, all code that ends visual mode must set vc.state = 'normal' before calling vc.done()
