Suggest capitalizing names of properties

[brianchaan]

I had used the following:

.addProperty('location', location)

to add a location to my calendar. It turns out that this works on Outlook, but not on Apple Calendar, which seems to require the property to be in all capital letters (ie. LOCATION). I'm not too familiar with the spec, but it looks like this is probably the case with all properties. I would suggest doing a .toUpperCase on the property name as a convenience.
