Title: add lots of important bypass capacitors to schematic only

i added capacitors that need to be there for the board to work well. okay, maybe it would work without them but it will work better (and make less electrical noise) with these caps.

if the stepper drivers have good caps on them on VMOT and 3V3 then you can skip those five of each, but the ones i added to the voltage regulators are important!

the ones i added to the 5V and 3V3 LEDs will accentuate current draws! and the 1K resistors are necessary if you want to be able to look at the LEDs and examine their brightness (which will indicate voltage well)

the 5V LED should be blue (they have a 3.2v drop) and the one on 3.3V should be red or green (2v drop)

sorry my pull request style is amateur.
