When payment is "pending" do not assign roles.

[becleung]

Adds some code in the after_all_level_changes function using pmpropbc_isMemberPending to prevent new roles from being assigned to user.

Changes proposed in this Pull Request:

Stops new roles from being assigned when membership is pending from using the Pay By Check add-on. This partially resolves issue #36. I say partially because this does not assign roles when payment is marked "success".

How to test the changes in this Pull Request:

1. Install Pay By Check add-on
2. Check out with a new membership level, use the "pay by check" option for payment
3. The new member that signed up using "pay by check" will now only have their old role(s) instead of being automatically assigned all the new roles that comes with their new membership level

Other information:

• Have you successfully run tests with your changes locally?
