Request - Make directory and git branch click events optional

[blkdr]

Add an option to let the user choose from what they want to do if they click on the directory or branch name.

Why? Some users may accidentally click on the directory or branch name and the plugin automatically open the directory or the browser.

Examples:

...
hyperStatusLine: {
  onDirectoryClick: 'none',
  onBranchClick: 'copyBranchName'
}
...

/*
  onDirectoryClick:
    'none'
    'copyDirectoryName'
    'openDirectory' // default
  onBranchClick
    'none'
    'copyBranchName'
    'copyBranchURL'
    'openBranchURL' // default
*/

none should be enough if copy to clipboard is not possible.
