Kelvin Sherlock ce1a36eba5 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.
