Edited multiserial sketch to be in a proper folder and also use the newer GEVCU4 values.
Merge branch 'WIP' of github.com:collin80/GEVCU into WIP

Conflicts: It didn't like that the multiserial sketch was moved. This commit should fix that up and merge me back into WIP properly.
Added the ability to set motoring mode to either torque control or speed control. This should be exposed on the web interface as well. Also did some minor formatting.
Updated multiserial sketch to work with GEVCU5 units with the new G2N1 modules. Also adding the firmware for those modules and the bootloader.
