This is just a bug fix release. The following bugs have been addressed:

The summary view was blank when sorting alphabetically (if sorting last name first)
Fixed incorrect species count for ABA v8.0.4 checklist template
Fixed a crash when deleting the only non-bird observation in a checklist

Also, when the species count is > 999, we now show commas for the count at the bottom of the checklist (e.g. 25/1,112 birds).
