Support capture groups for smart renaming

[dantechguy]

Unless I'm being silly, I don't think it's possible to rename the first space (" ") character in a title with a hyphen ("-") for example - as any capture which anchors to the start of the string will mean that from the start of the string is replaced.

I then guessed that perhaps this plugin allowed you to use capture groups to smart replace, so my above scenario might be solved by:

Capture: ^(?<start>[a-zA-Z0-9]*)

Replace: ^\k<start>-

This also didn't work, hence I'm suggesting it here! If my understanding of regex is correct I imagine it should be fairly straightforward to implement.

Thank you!

Look at #20. You have to use a different kind of capture groups.
