Use csquotes.sty and footnotebackref.sty
British English set where needed
Changed Hyperref options; links now hidden
French spacing
Removed hyperref options; set biblatex options and use \addbibresource
Use fontspec.sty rather than mathspec
Fontspec loads fixlatex2e anyway, so only needs to be loaded for pdftex
microtype.sty and upquote.sty are in TeXLive, so I'll assume they're available
Added option for arara rules
Added options for headers
Use parskip for paragraph spacing
Links are hidden anyway so no need to add that for TOCs
Removed unnecessary space
