add regular expression support for evaluate, if, etc.
...
eg:
evaluate abc =~ /(abc)®4/ # sets the '@4' environment variable.
evaluate abc !~ /[aA]bc/
MPW regular expressions are converted to c++11 std::regex regular expressions and evaluated.
Sadly, the // regular expression syntax interferes with unix-paths (if the / count is odd). quoting or ∂-escaping the /s is therefore necessary.
file globbing is not yet implemented.

rewrite phase-2 lexical analysis. It splits on ; ( ) || && and I've deferred the invalid string checks until later.

fix parenthesis processing. left-paren is only a command when it's argv0. Otherwise it's a normal character. (but must be balanced with right-paren to know when right-paren is a separator. ).
