Add more Common Name defaults to taxonomy.
Globally replace `idealien_rideshare` with `wp_seedbank`, capitalize class names and constructors.

:%s/spaces/quantity/g
:%s/event/common_name/g
:%s/departureDate/seed_expiry_date/g
:%s/returnDate/exchange_expiry_date/g
:%s/state_prov/genus/g
:%s/username/unit/g
Run SQL to rename post meta fields.
Rename "Trade" to "Swap", reorder so "Swap" is first in type list.
Rename 'idealien-rideshare' i18n references to 'wp-seedbank'.
