Simple annotation support for setting background colorings to days e.g. to present business hours or some other info.
Rest of the annotation related changes that I forgot to commit in the first batch.
Fixed styles a bit so that different backgrounds can affect how annotation looks like (e.g. current day has yellow background)
Small changes to make example more clear
Fixed few errors caused building to fail
Added compiled version for the people who doesn't know how to compile it by themselves.
Added required name and version attributes to package.json to prevent error while running npm install on OSX.
Fixed annotation view demo to work with latest master.
