Various UI issues: capitalization, organization, etc.

To follow Drupal conventions and English norms, all phrases that are not proper nouns should only have the first words capitalized. In this module, "Street Continued" should be "Street continued", and "Apt/Suite#" should be "Apt/suite#".

"Apt/Suite#" probably should not have the pound sign. Spell out number.

It's not clear what the "Other" field is used for.

It's not clear whether "Street" is supposed to contain the entire street address or just the number.

"Street" may be a confusing name when non-street addresses are used, like PO BOX. How about "Address line 1" instead?

"Apt/Suite#" only makes sense in the context of the street address, so it should be at the end of the address first line and not on its own line. In the same sense, you have city, state, ZIP, and country on the same line.
