Simplify version comparison and add c.isSupported()

c.isSupported([minVersion]) returns a boolean as to whether the current
session's Serrano version is within range as defined by Cilantro's
minSerranoVersion and (now added) maxSerranoVersion. An alternate
minVersion and maxVersion can be passed to isSupported() to denote
Cilantro has support for a Serrano feature introduced at a particular
version and will expose it if the active Serrano version being used is
equal or exceeds the specified version.

See the cilantro/utils/version module for details
Add version conditional around recent additions

Note, the conditional around the c.data.shared_queries will always
be false since the session is not loaded when the collection is
initialized. See https://github.com/cbmi/cilantro/issues/229 for
more details.
