First pass of adding direct DBC signal support to the graphing window.

Things that were planned for the GVRET-PC project but never completed.
Some notes on things I'd like to put into the program but haven't put on github (yet)
Single / Multi state - The goal is to find bits that change based on toggles or discrete state items (shifters, etc)
fuzzy scope - Try to find potential places where a given value might be stored - offer guesses and the program tries to find candidates for you
or, try to find things that appear to be multi-byte integers
Change dbc editor to be able to do multiplexed signals
Make the graphing window use signals either exclusively or as an option for each signal graphed
Allow multiple DBC files to be loaded in the program and also allow them to be associated with a bus
Allow scripts to read/write signals from DBC files
allow scripts to load DBC files in support of the script
