[webauthn] impl guidelines for signature counter

equalsJeffH has just created a new issue for 

== impl guidelines for signature counter ==
the spec lacks description of the significance, use, and management of
 the signature counter. 
Searching for ³counter² across the entire document only shows a few
definitions of counters, not any description of their use. [...]
And what about for assertion signatures ­ every time an authenticator
asserts it should grab the last counter, bump it, sign it, and store 
new value?
e.g., there could be some further language in the spec (eg Impl 
guidelines and sec considerations) regarding the signature counter.
