- 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.

This fixes lash so it handles environment variable expansion, regardless
...
of where the environment variables are located in an argument. This allows
things like 'echo foo$1$SHELL' to expand the same way bash would expand it.

Commit Vladimir's latest cmdedit. I modified it slightly to ensure
...
parse_prompt() would be called before cmdedit_init(), since cmdedit_init()
calls cmdedit_setwidth() which uses cmdedit_prmt_len, which is set by
parse_prompt(). Also, added a mod, so very narrow terminals should now wrap
properly... This is working very nicely for me -- Vladimir has done some
very good work.
