Project data table shows truncated hours

[cantsin]

At least one user has reported confusion about how we round up or display hours on the project page.

It turns out that when we make a project chart and table we explicitly truncate the hours by doing applymap("{:.0f}".format). I am not sure this is desired behavior, especially as we provide "export CSV" functionality. We probably want to display the fractional hours as well (:.2f).

FYSA DataFrame.applymap seems deprecated. We should be using DataFrame.map instead.
