[Tails-dev] Activating multimarkdown

Hi,

In the process of polishing the MAC address spoofing documentation, I
felt like adding a footnote. This is only possible if we enable
multimarkdown in ikiwiki, which is not the case so far.

I think that might be useful in the future, you can add footnote, layout
fancy tables, etc.

Shall I do that, or do you have any counter indication?
