This patch makes EntryListView responsible for providing the divider between
entries, instead of setting a margin on every entry like we do now. It also
fixes a couple of miscellaneous issues, like use of the old package name.
This fixes the following bugs:
- Sort category is forgotten after lock/unlock
- The sort mode is not respected for new entries
I got a little carried away while working on this patch and also included the
following other enhancements:
- Simplify the SortCategory, Theme and ViewMode enums
- Simplify usage of string resources
- Don't call notifyDataSetChanged and runLayoutAnimation unnecessarily
