Feature request: Web editor for Pirania splash page

[ilario]

Talking with Jesi at the BattleMeshV14 she requested a feature in Pirania:
the possibility to easily edit the splash page.

The splash page of Pirania (the one that appears when you try to connect to the internet) should be possible to edit by the local community easily via a web interface, for adding announcements and information about the local (virtual and physical) services. So a kind of very barebone editor that allows an admin to add formatted text (without needing to know HTML) in the splash page would be great to have.
