Edit all templates to honour the desire to omit the default datestamp

[mengwong]

Following from #4

Start by editing the included templates (inc_cover_jfdi and inc_cover_legalese) to not use <textvar name="Output Date" /> if the template spreadsheet has requested a custom date.

This should ideally be done in a standard way that maintains clarity of interface separation – a given XML template should know unambiguously what that override date variable is called. There may be a need for more than one custom variable (consider agreement_date vs some_specific_agreement_date).

this is the standardization we need to clean up
