- Add methods for VTodo and VJournal
- Changed the shared properties to be attached to the ComponentBase
  so those methods don't need to be repeated across all attributes
  that share them
- If a property is shared across some, but not all components, then
  it's a private method on the ComponentBase and public method on
  the Components (eg LOCATION for Event and Todo but not Journal)
- Shifted position of some Event methods in the file to live after
  the VEvent struct

- Add methods for Alarm, Timezone, and FreeBusy
- Only methods for creating and adding right now, will add methods
  for the properties unique to them later

- Recursive call for Alarms
- SetGeo was not a public method
- Missing comma in struct creation
