breakup the Arduino_WS_Webpage template

# Idea
turn it into multiple simpler templates
to be honest it's "serial communication" + "web socket" + (optionally HTTP)

# Why
- it's easy enough to tack them onto each others to get back to the whole thing
- you'll have to tweak each pieces anyway to make sure "the piping" is lined up properly
- we're not storing two ways of doing the same thing
