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.

script support. scripts run with an independent copy of the environment and aliases. local variables are not imported.
...
Currently, it for a ".text" extension to check if it's a script; this is a placeholder.
