Travis: use Precise infrastructure and update Build Matrix (#179)

* Travis: use Precise container-based infrastructure

* Travis: Explicitely require android-15

* Travis: Update build matrix

* Travis: Explicitely require android-23

* Travis: Require current target and relevant sys-img

* Travis: Require platform-tools

* Travis: [debug] list targets, reference android-24 first to investigate

* Travis: rollback matrix, list sdk components, add second tools in components

* Travis: remove "-no-audio" parameter from emulator call

* Travis: [debug] try explicitly listing *android-* rather than using variables

* Travis: Use GAPI image instead of missing sys-img-armeabi-v7-android-23

* Travis: Use ABI default/armeabi-v7a for API 23 Gapps

* Travis: Use android-23 with ABI=default/armeabi-v7a

* Travis: Specify armeabi-v7a for all system images

* Travis: Target android-17 instead of 23 until #188 resolves
