Progress on #90. Changed ButterflyManager so filter will sort by
family first, then by butterfly name, with an exception to the
butterfly name "Unknown", this will be put be sorted to the
top of the list. This will then be used as the seperator for
familys. Can do something similiar for unknown Family.

For this to work I need "Unknown" butterflies added to the
database for each family type, and an Unknown family type added.
