[Templates] ical formatting filter

[Nigel Metheringham]

I've got some slightly crufty code in a site of mine that handles
generation of ical files - using TT.

One of the things that was tricky about that was getting the very basic
file format and line wrapping stuff right, and I ended up producing a TT
filter plugin to do this - specifically to:-
  - Ensures lines are no longer than 72 chars
  - Continuation lines start with a single space
  - Blank lines are removed

I'm about to be revisiting this stuff, and if there is any interest I
could clean it up a little and put it up as (I guess)
Template::Plugin::IcalWrap

So, is there any interest?
