Vue path #28
This may not be the best way to do this -- but it worked well for me. Right now the "/tinker" path is easily changable the Larvel config, but hard-coded in the Vue file.
Changing that to "window.location.pathname" should let it work from any path configuration -- or in my case, when Laravel is running in subdirectory. (In that case, the Laravel path setting will not match the POST URL.)
