Log Message:
Update ruby-rb-fsevent to 0.10.2.

v0.10.2							2017/07/01

While procs are flexible about arity, lambdas and converted methods are not.
Thus passing in two parameters broke any such callbacks.  The only change in
this release is that callback block arity is checked before passing in any
values.

v0.10.1							2017/06/30

* rebuilt fsevent_watch against 10.8
* fixed documentation

v0.10.0							2017/06/30

* MacOS 10.13 specific flags added to compatibility code
* Added second parameter to callback with more detailed event info
* Switched communication format to OTNetstrings, fixing a bug where some
  events were ignored if they contained certain characters
* Removed custom path fixture from tests as there have been complaints about
  using the gem with maven (??)
