add new pattern option

[sebastianlarisch]

This PR adds new option pattern which can be used in actions, e.g. prepare-commit-msg hook. It allows to not just prepend the subject of the commit msg with the ticket number, but also allows to add delimiters (here a colon) or other text.

Example:

Branch: feature/ABC-123-my-refactoring-branch
Commit-Message (before hook): "Some refactoring"
Commit-Message (after hook): "ABC-123: Some refactoring"

{
    "action": "\\CaptainHook\\App\\Hook\\Message\\Action\\InjectIssueKeyFromBranch",
    "options": {
          "regex": "(([A-Z]+-[0-9]+))",
          "pattern": "$1:",
          "into": "subject",
          "mode": "prepend",
          "force": false
    }
}

Looks good

I cleaned up a mess I created there as well and moved some comment detection functionality to the git library.

During this I found a magic space appearing even if prefix is empty.
I fixed that and now if you want that space you have to explicitly configure it.

So if you do not configure a pattern and no prefix or suffix I still add the "magic" space.
But if you configure anything you now have to take care of all the spaces.

So you need to include the space in the pattern config as seen below.

{
    "action": "\\CaptainHook\\App\\Hook\\Message\\Action\\InjectIssueKeyFromBranch",
    "options": {
          "regex": "(([A-Z]+-[0-9]+))",
          "pattern": "$1: ",
          "into": "subject",
          "mode": "prepend",
          "force": false
    }
}

Thanks again 👍
