Payments Modal Improvements

[OzzieOrca]

@adammeyer what do you think of this? Let me know if you have any issues or questions with the changes.

Changed/added:

• Add registrant names to top of payments modal. Helpful to make certain you are entering payments for the right person and have clicked the right payments button.
• Remove duplicate timestamps from payments tab when editing and made form fill entire width.
• Fix spacing issue causing horizontal scrolling. This is the issue you messaged me about. Added col-xs-12 (https://github.com/CruGlobal/conf-registration-web/compare/responsive...payments-modal-improvements?expand=1#diff-0bf940ea2c79575d8a4dc75cbd019e4eR143) to add the 12px padding it needed for the form-group's -12px margin not to extend beyond the table
• Changed step to 1 for currency values. (adjusting a payment/expense by cents doesn't make much sense.)
• Made expenses tab editing happen inline. I think it makes it clearer what is being edited. Before the added row looked weird being a duplicate.

Other thoughts:

• It might be nice to make the payments tab do inline editing also but there are several payment types that need lots of inputs. Could potentially do it inline for the ones with just a cost and description.

Thanks @OzzieOrca. This looks great! The payments tab used to be editable inline but was changed when more fields where needed for scholarships and transfers. Didn't look right.
