Track intended payment method on schedules (pledges, recurring, membership) rather than just autoprocessing method

Currently when you create a schedule the Method field indicates whether you want the system to automatically process the payments. The options are none, EFT, and Credit Card. If you select EFT or Credit Card you are required to input the payment details.

This causes confusion for two reasons:

1. The Method field on payments indicates how it was paid, regardless of whether the system automatically processed the payment. For example, you can indicate that a payment was made via credit card but not processed by Bloomerang.

2. If you know the payment method a donor intends to use for their schedule but it won't be autoprocessed, you would have to track that in notes or a custom field instead of using the Method field.
