Add 'ss05' which maps all of U+0020..U+007E to SAA5055 glyphs

This seems appropriate for something that wants to treat these as ASCII
glyphs with their ambiguous semantics.

This uses the existing apostrophe.curly, and also adds grave.curly (an
alias for quotereversed) and bar.broken (an alias for brokenbar).  Of
course there are also 'cvXX' features to enable each one individually as
well.
