And another new Biologer for Android

This is a very nice bugfix release created during my process of learning Java :) Now we have:

- Fix for a major bug sending wrong data and image license to the web! Please send us a message if your data are not licensed correctly.
- Option to select a database from the login screen.
- Even better App design.
- Fix a messy coordinate input, that caused some data to get Lon Lat value of 0.
- Fix a bug that caused coordinates to be overwritten when editing an entry.
- A lot of other small changes...
