Title: Remove link to sinatra-synchrony gem from README

Since the author won't be maintaining the sinatra-synchrony gem and recommends not using it, we probably shouldn't be linking to it.

From the sinatra-synchrony README:

> This gem should not be considered for a new application.
...
> I will not be maintaining this gem anymore.
