Minor cleanup of Clojure example.

Cleaned up some formatting and spacing. Used future-cancel. Future
subscriptions were not being returned properly. Replaced use of #_ with
comment form. Fixed rest args usage for hello example.

Minor cleanup of Clojure example.
scala support in examples
Commenting out non-deterministic portion of unit tests

These verifications are non-essential so commenting out right now until I or someone else has time to fix it correctly.
scala is building
Eclipse build config

- Include 'provided' in Eclipse classpath
- Upgrade to Groovy 2.+
Remove scala from rxjava-examples

Groovy and Scala can't co-exist in a single Eclipse project even though Gradle handles it fine.

Perhaps the examples should go in the /test/ folder of each of the rxjava-[language] projects instead of rxjava-examples?

Code cleanup
migrate unit tests for Groovy to separate Groovy file

- testing all Groovy functionality doesn't belong as an inner class
- it was awkard to load Groovy scripts via Java (leftover from previous codebase where Groovy wasn't part of build, only a runtime library)
- establish convention for each language to have a suite of tests in /src/test
remove rxjava-examples

Examples have been moved into /src/examples folders of each language-adaptor subproject.
