[O] org-date-toggle-inactive

[Johan Sandblom]

I wrote the following which allows me ctrl-c-ctrl-c on a date in an org 
file and thereby toggle the inactive state of the date. I find it useful 
when applying to courses that I am later [not] admitted to. Perhaps it 
is useful to someone else. Perhaps also there are obvious improvements 
to the code. Lastly, perhaps there is a better place to submit such 
snippets. I appreciate feedback.

Regards, Johan
