delete ancient runall.sh and run.sh scripts
Allow renaming exprs to have multiple parameters in their channel
specifications.  Also clean up the varsetName rule slightly.
Close #214
Allow for a succession of process/action suffixes (Fix #157)
(+ whitespace normalisation)
Cause an exception for actions like `a.b.c` - there is nothing that can
be instantiated to in the AST.  (Actions that are just a single
identifier are fine.)
Rework a sticky section of leadingIdAction to handle the case for action
references and operation calls better.  Partial solution for #209 (now
needs the typechecking sorted out...).
Coalesce two similar error cases (as they were essentially the same
problem relative to a user's intent).
