WHAT on Modules

I've made a small change to WHAT to make it easy to see functions defined within a specific (named) modules.

For example, in the current graphics module (which is still be moved to the host-kit so only contains a few functions at this time):

>> what graphics
box              Draw a rectangular box.
circle           Draw a circle or ellipse.
do-events        Waits for window events. Returns when all windows are  closed.
fill-pen         Set the area fill pen color.
handle-events    Adds a handler to the view event system.
handled-events?  Returns event handler object matching a given name.
init-graphics    Initialize graphics subsystem.
init-view-system Initialize the View subsystem.
pen              Set the line pen color.
show             Display or update a graphical object or block of them.
unhandle-events  Removes a handler from the view event system.
unview           Closes a window view.
view             Displays a window view.

Here's an example of the HTTP protocol module:

>> what http
check-data
check-response
do-redirect
do-request          Perform an HTTP request
http-awake
http-error          Throw an error for the HTTP protocol
make-http-error     Make an error for the HTTP protocol
make-http-request   Create an HTTP request (returns string!)
parse-write-dialect
read-sync-awake
sync-op

This comes in handy.
