Add Daily Usage tab to Resource Usage panel

Added a new tab to Resource Usage panel. This tab prompts the user for
timeframe and then generates a report showing daily usage per project over the
indicated time frame with one table per project. This report shows all meters
collected summarized per day.

Originally I generated report with default settings initially but opted to only show
form first so that panel can load quickly.
