Various improvements and fixes

nibras-reader-android.apk,
nibras-bundle-linux.tar.gz,
nibras-bundle-mac.tar.gz: the file containing the complete environment to start Nibras for Windows, Linux and Mac. Note: the mac bundle was not tested. It consists of the (test) Linux environment with the JRE replaced with that of the Mac.

nibras-reader-android.apk: Due to Android 10 new policy, the Google Play version of Nibras Reader cannot connect to Nibras PKM (on the desktop). This is why a non-released (i.e. production) version is needed, and so, a manual installation of the .apk file is required. Be sure to give it a "Storage" permission if you want it to open the records files.

nibras-reader-browser.zip: A browser version of the Nibras Reader. It is included in the bundle and can be accessed from: https://localhost:1441/.
