Make Mac USB Driver Installation work properly without need to reboot

[PropGit]

Explore, and if practical, make Mac installer unload Apple's "FTDI" USB driver and load FTDI's USB driver instead. This should remove the need to reboot the system after installing the BlocklyPropClient with FTDI drivers.

A question is whether or not the load/unload operation is even possible without superuser privileges.

Recent evidence and conversation about macOS Sierra+ reveal possibility that Apple's FTDI driver needs to either be used exclusively (ie: don't install and use FTDI's driver) or that it should be permanently disabled. This needs to be explored and resolved before this issue can be performed.
