Workplace.type

Implemented Farm.type and Factory.type to take out the WORKS constant
in the display module.

Prep for major overhaul to implement SimState class.
Multiple Things

- changed name of type attribute of workplaces to name
- improved readability of display module code
- updated display module function pDisplay to take a list of workplaces
instead of individual workplaces
Workplace object list implemented

Functions previously taking certain workplaces have been modified to
take a list of Workplace instances as an intermediary step to
implementing the SimState module.

Two birds, one stone: cleaned it up so it was legible and made it work
with a list of Workplace instances.
Dynamic robot placement command list
