[Web] Next layer processing fix

Fixes up the samples index and connectivity a bit and corrects the fix to not break the desktop OSK.

Fleshed out the CAPS layer of the testing keyboard - all CAPS-affected keys now do special CAPS printouts to prove the layer differentiation.

Initial fix for #116 - turns out that we had an unnecessary next layer check earlier than it needed to be.  Removing that fixes the issue.

Main thing now:  fleshing out the testing keyboard to make the tests a little simpler.
