organize qml files in subdirectories

This makes the organization of the qml files a bit more fine-grained, it
prevents mixing of .cpp and QML files, and also of what's compiled, and
what's included in the app as qrc data.

In particular:
- subsurface specific QML items go into the qml/ subdirectory
- theme and unit definitions to into qml/theme subdirectory (they
  already were located in a theme directory)
- generic components, such as our Label goes into qml/components

This facilitates sharing of functionality and identifying common stuff
better. Ideally, we can pull qml/theme and qml/components from a
standardized set at some point, so we don't have to maintain that code.
