Title: Allow qstr's with non-ident chars, construct good identifier for them.

Also, add qstr's for string appearing in unix REPL loop, gross effect
being less allocations for each command run.

Just to clarify where this comes from: Mission: make tapping just enter in unix REPL loop to allocate as little memory as possible. Together with #214, this is now down to ~57 bytes per iteration.
