Align both iOS and Android on the same version

To simplify the releases, we may try to use the same version and release both apps always at the same time.

Only major and minor versions are updated after a "main" release.

We still need to be able to release and push a fix on one application:

• do a patch version
• release the codebase
• push only one app on the needed store

This would allow us to have only one Jenkins job to do both beta releases and one for the productions releases. We will keep the existing ones to be able to do patch releases on a given OS.

Pushing on the branch release/beta would trigger both beta jobs.
Launching the nuxeo-mobile-production job would trigger both production jobs one by one with the right parameters (RELEASE_NOTES_JA_JP for android, RELEASE_NOTE_JA for iOS).
