Adds Pedal Fingerprints for Honda and small change to Pilot / Ridgeline steerKpV and steerKiV to fit 3.3333 ratio

[jfrux]

This is based on Joel's Pedal PR but should contain changes from #251 0.4.7.1 release.

• Updates Acura RDX Fingerprint Changes to Support Comma Pedal
• Updates 2017 Honda Pilot Touring & 2016 Honda Pilot EX-L Fingerprint Changes to Support Comma Pedal
• Updates Pilot & Ridgeline steerKpV and steerKiV to match the 3.3333 ratio of the other Honda vehicles.
• Adds comments to selfdrive/car/honda/values.py to explain the Pedal changes.
• Get response on questions from @rbiasini relating to comment formatting, and fingerprint formats.
• Verifying the steerKpV and steerKiV changes I made on my drive home today.
• Fix issues with minimum steering speeds not showing steering warnings. Mine is the Pilot and it's not showing the warning anymore below 12mph.

@jfrux looks good. Can you please add a comment that 512 and 513 are reserved comma pedal? Also, I would prefer to leave the toyota changes out for now, as pedal isn't supported for toyota vehicles yet.
Other than that I verified that the changes are as intended, so it's good to go.

@rbiasini Do you want the comments + the 512, 513's to be on a new line similar to how the sent messages were before?

Going with option 2 for now until I hear back.

Another question, should I add logic for Pedal support and stop_and_go variable in interface.py
You would think that cars with Pedal would need to have different settings in some areas?

[jfrux]

Okay so we still need to warn steering on cars that have a cut off on steering at the ECU.
The pilot has a cut off on steering at 12mph so I need a warning to throw.
It appears that something changed in 0.4.6/0.4.7 that has caused this experience to go away.

It now just shows as engaged always down to zero.
