absolute path and path regexes do not accept file/folder names with `.` in them

[slacksystem]

Hi, I've been trying to use the quickcopy feature and it does not recognize paths with folders or files beginning with .. As many important dotfiles and other configuration files start with these, including the main .tmux.conf in most cases, I think it's important to allow for paths that include these names. I'm happy to tweak the regexes and make a pull request, but I wanted to first make sure that that would be a change you were willing to accept. I think it would improve the quality of the plugin and account for a frequent use case.
