Regular expressions are not supported

[dan-gph]

In the Bash version of z, you can match using regular expressions, so for instance z c.t would match on cat and cot. This feature does not appear exist in the PowerShell z, or if it does exist, it doesn't work on my system with z 1.1.13. I simply get a "Not found" message when I try it.

Yes, regular expressions were on my initial feature list when I developed this, however, I got lazy since standard directory lookups have served my needs up until this point.

Happy to accept a pull request for this feature:)
