Some more work on the run interface.
CharmDefinition: _call_ `options.sort` (don't just reference it)

Really, shouldn't Python warn me about this?  Its proponents take the
language seriously enough...
make-host-index.py: corrected format string
option.py: use custom text-wrapping func. instead of TextWrapper

TextWrapper was being stupid.
option.py: added support for named option "sections"
sshconfig.py: don't try to read user's SSH config if it doesn't exist
renamed: chimi.config{.HostBuildConfig=>}.get_architecture()
