Merged WeatherData into project.
Added ability to select calendar, collect events from selected calendar.
Added feature to collect events and list events at set time.

Next TODO - set a range based on current date. (self query: System date or configurable?)

Files added:
EventListing.py - manage and store events required for the alarm clock
WeatherParser.py  - parse XML file with more fitting English instead of short form
