- Changed name of BB_FEATURE_SIMPLE_PROMPT to BB_FEATURE_SH_SIMPLE_PROMPT

 - Set BB_FEATURE_SH_STANDALONE_SHELL and BB_FEATURE_SH_APPLETS_ALWAYS_WIN to
   be off by default
 - Set BB_FEATURE_SH_SIMPLE_PROMPT to be on by default
 - Added some more magic to the Olympus section to make all the dependencies
   on the shell, cmdline editing, tab completion and friend work properly.
 - Tidied up the Olympus section with some whitespace. Checked the various
   scrips that parse through there and the extra whitespace shouldn't break
   anything.
