FRG support of multible subreports instead of merging them all into 1.

[Frustrated-Programmer]

Fixed issue of multiple sub-reports using the same data merging into a single sub-report. This hopefully will partially fix #197 however my next PR should fix it entirely.

Also included naming subreports since in the GUI having multible subreports gets confusing, so each section uses a numerical system to identify itself to the user. "Subreport 2's Detail(emphours)" instead of "Detail(emphours)"
