Julia frontend

This is a draft for review - let me know what you think, and if we decide to go with this concept we can add dynamic code.  The timeline functionality could just be a display of the comment feed with repayments and reschedule events added, maybe the last five or ten events only.  Probably no need to fix it to the top since it will be a longer panel.

The repayment schedule is not displaying the top border of the <td> on the right side - I didn't manage to fix this.

I'd suggest using $ instead of USD for dollar amounts throughout the new site, as that seems to be standard practice even for international sites.  For borrower currencies, we should use the three-letter abbreviation and round to the nearest whole number.
