Qt Quick Controls Calendar

[Mitch Curtis]

Hello.

At the beginning of this year I started work on a Calendar for Qt Quick 
Controls as a sort of side project. After removing the "WIP" from the 
commit message, I got some feedback from developers who either a) had 
also wrote a Calendar for KDE stuff or b) suggested I ask for feedback 
from plasma-devel. Rather than add to the already massive list of patch 
sets for that change, I thought it would be better to truly open up the 
Calendar for contributions before it goes in by creating a WIP branch 
for it in the Qt Quick Controls repo [1]:

wip/calendar

It'll be a throwaway branch, so every commit must be atomic and follow 
all of the normal Qt commit policies [2][3]. At the end, we'll resubmit 
every individual change to qtquickcontrols' dev branch.

Please feel free to submit patches or provide feedback on what's already 
there. For example, it has already been suggested that there should be a 
C++ backend for the models, dates, etc.

Cheers.
