iCal extension

Hi,
I created an iCal extension to PopClip, it can add selected text to iCal as event or todo.
It extracts datetime from the text, the first one will be used as due date of the event and todo. 

  At this time, two datetime format is supported:
  1. [YY]YY-[M]M-[d]d [H]H:[m]m. '-' may be '/'
  2. [YY]YY年[M]M月[d]d日 [H]H:[m]m

And I don't know why yet, applescript reference examples, such as `date "Friday, November 9, 2007"` and `date "8/9/2007, 17:06"` failed on my Mac ( Chinese language ). Maybe you can improve it to support more datetime formats.

Hope you will like it.
