suggestion: continuous integration & automate maven publishing (#38)

* added android travis.yml

* update ndk to r16b

- adding cmake
- adding swig
- using env var for location of pocketsphinx and sphinxbase

https://github.com/googlesamples/android-ndk/blob/ba6a5a46cf5c0d4b76e2d56a78f321e4668e6e26/.travis.yml

* publish to bintray

* diff showing what config to create
