Filter user input switch signals

Description

The user input switches could use some filtering between the physical switch and the micro. This filters the high frequency content from the switch event from reaching the micro, and debounces the signal.
The schematic symbol for the switches should also be updated to be an actual switch symbol. Right now it is a generic connector.

Suggested Solution

An RC filter on each switch signal is pretty easy to add. A simple 100R/100nF would probably do just fine.

Thanks for the note @unpaid-bill! I agree, would be good to add this. I believe we're doing some software debouncing in Photon that would be nice to remove. We're very tight on available board space, so ill try to squeeze these in after other board edits are made for this rev. And agreed, a proper symbol should be used for the buttons!
