Standardize "systemDeviceNameConvention"

[WasabiFan]

We currently have systemDeviceNameConvention values in two forms: some of them are just a wildcard (*), while others are something along the lines of motor{0}. I'm not sure we even need this value anymore; originally it was there for parsing indices out of device names, but that functionality can be done other ways and I don't think that that property is actually useful. The main reason I can think of to keep it is to differentiate between things like linear and rotational motors, but to do that we'd actually need to standardize on a format.

Thoughts?
