Payprocc

OK, I have fixed contribution and event pages to not rely on javascript for their basic functionality.
Because it is so late in the pre-release cycle we need to thoroughly test this. I have done quite a bit and all looks good but could use a second (or third) pair of eyes to double-check the following are all still working correctly:
- Paid events with single and multiple processors
- Unpaid events
- Contribution forms with single and multiple processors
- Contribution forms with an "on behalf of" organization profile (test both required and optional settings)
- Contribution forms for free memberships or 100% discounts
- PayPal standard/express
