Fixes#206. Two other small fixes too:
* Units don't really translate, and they are appended to java strings anyway.
If it is to be translated, do a proper formatted string.
* Placed the light theme above the dark one, since it's the default.
- use 'com.android.support:appcompat-v7:22.0.0' instead of version 20.0.0
- ActionBar color: "F-Droid Blue" (also option for "F-Droid Green")
- fix invisible swap button with Material Design
- remove "Light + dark action bar" theme (as of Action Bar is always blue/green)
Android's lint will give warnings for all strings that are not translatable
or translated. Some strings like repo name/description and language codes
should never be translated. Here's how to officially mark as "do not
translate":
* for individual strings, include: translatable="false"
* for the entire file, name it: donottranslate.xml
