fixing get name applescript

- compiling it
- including source
- this runs with latest iTerm2 master
  (https://github.com/gnachman/iTerm2/tree/120a948cda36ac7e8040089b13a04c91a23fcf95)

This fixes part of the problem I raised in issue https://github.com/zephod/vim-iterm2-navigator/issues/2

However for me it's not working at all when trying to use `Ctrl` as the modifier key, i.e. `Ctrl-l`.
Also it just skips vim splits unlike I'm used to the same solution in tmux.

Thought anyways you may find this fix useful.
