Allow setting dob and country from CSV (fixes #40)

Although the CSV parser passes all named columns through to the builder,
that method only applies username, email and password. In addition,
PtcSession within the API module forcibly overrides any set values.

This applies `dob` and `country` if they're set in the CSV, and updates
the API module to use any value set in `account` VS hardcoded values.
