Issue 523

While comparing the useragents in my database between Browscap and Wurfl I found a lot of differences. This PR trys to fix some of them.

Changes:
- added Android 5 for the first Device I found
- added iOS 8.1 to the Google App
- removed some duplicate entries
- removed Firefox <4, Iceweasel < 4 and IE < 8 from lite file
- moved rules from `palm-web` to `wos-browser`

This should solve Issue #523.
