Support custom paired delimiters

[NikolaiKircher]

Use Case:

Given(/^We navigate to the homepage$/) do
  driver.navigate.to "http://google.com/"
end

I would like to be able to comfortably select the text We navigate to the homepage

Solution: Custom paired delimiters

One possible solution would be to introduce the ability to define custom paired delimiters

Similar to the way take inside box works - it selects everything between [ and ], i would like to be able to define a new paired delimiter.

e.g. take inside regex should select everything between ^ and $ or maybe even with multiple characters: take inside stepdefinition to select everything between (/^ and $/)

Question: do we want to support wrapping with these by default?

See also #335. I think the differences here are the following:

• These pairs would support different opening / closing delimiter, whereas #335 requires them to be the same
• These pairs require the user to configure them, whereas #335 defines a command for on-the-fly pairs

Question: Should custom matching pairs affect/modify the pair/any scope?

[pokey]

No, I don't think so.
