shell: remove

bb.shell is unused and incompatible with current bitbake.  We can resurrect it
in a more functional form when we add the text input to the goggle and ncurses
UIs.

-BitBake Shell
-
-IDEAS:
-    * list defined tasks per package
-    * list classes
-    * toggle force
-    * command to reparse just one (or more) bbfile(s)
-    * automatic check if reparsing is necessary (inotify?)
-    * frontend for bb file manipulation
-    * more shell-like features:
-        - output control, i.e. pipe output into grep, sort, etc.
-        - job control, i.e. bring running commands into background and foreground
-    * start parsing in background right after startup
-    * ncurses interface
-
-PROBLEMS:
-    * force doesn't always work
-    * readline completion for commands with more than one parameters
