add -d and -s to show/set default paths

[TK Soh]

Thought it should be more convient than having to manually edit hgrc, and user
shouldn't need to be aware that symbolic name 'default' carries a special
meaning. Though I seemed to recall Matt saying it's bad to have Hg editing the
file.

The code to change default path was taken from Bryan's recent fix on multiple
paths section.
