Export Metrics to CSV

A new menu option to export the ride metric data
as a CSV format file for manipulation in tools like
Excel.

It exports all rides (no date range) and outputs the
date in US format month/day/year, with time in 24hr format.

Additionally, a 'hack' to export all rides in GC format has
been removed since it was erroneously included in the initial
v3 branch.
