Enable date-based archiving/hiding of history

[kaihoffman]

Is your feature request related to a problem? Please describe.

If history is set to visible, it is viewable either by month/year or paginated. This goes as far back as the updates go, which may contain older, immature/development-era issues that make the incident history look worse than it is.

Describe the solution you'd like

An option to set a numMonths or similar from a date of incident to not display an incident in the history. This could therefore show only e.g. the last year of incidents for a cleaner look.

frankly this is hard to achieve because you need (a) to rebuild the site for changes to take effect, (b) incident history could just be hidden under a link.

i see the point though. I would accept a PR
