DEV: Updated report header to reflect the repository or log file analyzed instead of repeating it across all graphs & charts. Replaced static report title SVNstat with report header's value to make multiple browser tabs with different SvnStat reports easier to identify. Refined all-user graphs & charts' default titles for clarity; similarly refined per-user graphs & charts' default titles and ensured that their titles indicate the users to which they relate (e.g. "Commit times for j0e3gan") - for clarity where scrolling cuts off username headers above related per-user graphs & charts. Re-ordered all properties to better align with the order of sections and the graphs & charts therein in analysis reports.
