[O] New iCalendar import script

[Simon Thum]

Hi all,

I've written an iCalendar import script in ruby (I know, not emacs lisp, 
but at the least I should let you be aware).
I think it's an improvement over the awk script, so you may consider 
mentioning it in the appropriate places. See
https://github.com/simonthum/ical2org

It has more complete iCalendar support, in particular repeating dates 
and Todos. Likely it is easier to adapt to individual requirements. 
Also, it works under windows and linux - my win32 awk was missing key 
functionality for the script (mktimestamp, IIRC).
I'm not particularly attached to CC-BY or github, so if you think a more 
appropriate long-term place would be orgmode.org then we'll probably 
find a way.
It's in its early stages, for example I'm quite unsure about the 
timezone support, so feedback is more than welcome!
Cheers,

Simon
