[interfacekit] Server Tasks

Well, here's the first candidate for app_server M1 - a grouping of the server 
tasks. Please submit any others you can think of. I'm going to need them to 
be able to work on the interface spec

--DW


Messaging
---------
receives and redirects (dispatches) messages from the input server
responds to messages from apps
consolidates paint messages from apps
receives requests from BView, BWindow, BBitmap, and others to draw stuff 
(draw bitmap, etc)
creates ports for itself so that apps can communicate with it

Process Management
------------------
loads/kills processes
provides workspace support
detects absence of Deskbar and/or Tracker and restarts when necessary
detects absence of Input Server and restarts when necessary
creates a connection with BBitmaps requiring a child view

Graphics
--------
draws the blue desktop screen
provides functionality to the BeAPI for drawing primitives, such as 
rectangles, ellipses, and beziers
manages window behaviors with respect to redraw (move to front, minimize, 
etc)
returns a frame buffer to direct-access classes
loads graphics driver
caches fonts for screen and printer use
draws text and provides other font API support for the BeAPI classes
