ICS feed endpoint for integration in external calendars

[Florian Berger]

Users of my trac instance would love to be able to have tickets show up in their calendar applications (e.g. Thunderbird Lightning).

Trac offers an ICS feed of roadmap milestones. However, in our use case this is not feasible: My users don't aggregate tickets in milestones, but spread and shift them all over the place.

Since this plugin already does queries and calendar listing, it would be awesome to get the result not only as a visible calendar, but also as an ICS feed with a fixed URI that can be added to calendar software.
