add by-person itemization of hours on on invoice page

[tobiasmcnulty]

We received a request to itemize hours by person for one project . You can sort of get that from the project timesheet, but that doesn't show billable vs. non-billable (in sum). In the interim I am copy/pasting hour detail out of the invoice page and into a spreadsheet to sum them by person, which works okay for now but is not great long-term.

To clarify, how detailed would the per-person hours be? On the invoice page, we break down billable/non-billable hours into further detail. But for this feature request, it sounds like this level of detail would be sufficient:

	Billable	Non-billable	Total
Sam Blue	9.5	2.7	12.2
Ryan Green	10.1	3.4	13.5

That looks good. As an alternative you could also list out people and hours under the existing Billable and Non-billable headers, side-by-side with the existing listings by activity. You'd lose the the total hours per person this way, but that's probably not needed for invoicing. Either one will work fine for our purposes, so I'd say whatever you think would look best on the page.

In either case it would be nice to have the people list(s) sorted alphabetically by last name rather than by total hours (the way they are on the project time sheet), to help avoid copy/paste errors on invoices when the order changes between months.

Thanks @rebecca-caktus for your help with this!
