Version 0.4

This is a WORK IN PROGRESS release of the app. Feel free to use it (you can download the APK below), but do keep in mind that there could be major changes in the future that would make new versions incompatible with export files from v0.4.

This release fixes some bugs, makes a few UI tweaks, cleans up a lot of code, improves the way data is stored and exported (v0.3 exports are not compatible with this version) and adds the following features:

1. Allow editing stat types. This has a dedicated screen now.
2. Add stat type setting that enables the addition of multiple values.
3. Show the best value, the average and the sum of those values, if they are numeric. Each of these can be toggled on/off.
4. Add stat type setting that tracks personal bests based on the lowest or the highest values (user-configurable).
5. Allow reordering stat types.
