......................................................................
Follow-up: Further simplify splitting of reading lists.
Nothing wrong with the previous patch, but I saw a couple more
opportunities for optimization/simplicity:
- Move the logic to show the AlertDialog to BaseActivity, since
BaseActivity already contains the logic to register for other types of
Bus events.
- Simplify the logic of reshuffling super-large lists. It no longer
requires any manipulation of ArrayLists or recursion.
- Don't use a string resource for the renamed names of lists. This is one
particular case where we might not want to "trust" the translations to
follow the formatting that we expect. If a certain localization
translates this string incorrectly, then the procedure of renaming the
list might fail.
