Regex feature searching

[einstein95]

As it says on the tin, searching features using regex. This can be a checkbox to use regex instead of regular searching. Example uses for this are searching for "one" without results for like "opponent" (\bone\b), and "enter" optionally followed by "s" (enters?)

Unfortunately we would need something for the database to enable this feature, I don't think there is a way to code that.

Anyway, you can already achieve almost the same results with the current syntax:

• searching for "one" without results for like "opponent" (\bone\b) => " one "
• "enter" optionally followed by "s" => " enter " | " enters "
