I've added a test for #2 changing "credit card" to "card" since it's a great way to show the use of translations.
I added all the english translations into one file
I added some attribute translations for the method and value selectors in the create donation page so that "credit_card" shows up as "Card"
TODO:
[x] more organization is needed in the en.yml file
[ ] There are a lot of strings that are hard-coded in, like the "Name:" text on the show pages for a donation. The forms labels look for their values from the localization files but the show pages don't
[x] probably other stuff that I don't have in mental model, just figured I'd start as it's easier to get things done with some crystallization point of action
Fumbling around with translations.
