Peter Serwylo 0f64f2c181 Clarify threading when loading categories
Previously, it was not explicit that the `onCreate` happened to be invoked
in the UI thread. Now it is, due to passing `new Handler(Looper.getMainLooper())`.
Also, the categories are now loaded in a background task, and then the UI is
updated on the UI thread.
