Add Span to Sampler method params

Browse Source 
Also allows us to actually create a PercentageBasedSampler (I
don't think anyone tried it before) without resorting to
lazy beans and proxies.

Another freature added here is a default percentage sampler
if we know that spans need to be exported (zipkin or stream
is present).

Fixes gh-138
