Weekly Update 

* Handle Some Settings Better
* Better Parameter Detection
* Implemented Event IDs for Event Operations
* View an Event's Details
* Delete Events
* Display Help
* Show approximation of some Calendar Colors
  (This is kind of a mess, since I'm converting web hex colors to 3 bit
  ansi, so it's not done)
