'light' script always opens a new window

Bug Report

'light' script always starts a new window. I'm not sure if this is a bug or a feature but it would be nice if it would always open files in the same window, or if there was an option to do this.

Steps to Reproduce

1. To make sure the install is clean, delete the lighttable directory in /Applications and delete "~/Library/Application Support/LightTable".
2. Download lighttable-0.8.1-mac.tar.gz from LightTable website. It will extract automatically to ~/Downloads/lighttable-0.8.1-mac/
3. Move lighttable-0.8.1-mac dir to /Applications.
4. Start LightTable with <command>+<space> lighttable <Enter>.
5. In terminal window, in home dir, run
   • /Applications/lighttable-0.8.1-mac/light .bashrc

This will start a new window with .bashrc. Repeating the script call will always open a new window.

Environment

Info	Details
Light Table version	0.8.1

Error Messages

On first startup with command+space method:

Failed to open path '/Users/chris/Library/Application Support/LightTable/ltcache/default.clj' with error: Error: ENOENT: no such file or directory, open '/Users/chris/Library/Application Support/LightTable/ltcache/default.clj'

Later starups using the command+space method produce no errors.

Terminal output when calling the 'light' script:

Unfortunately, I do not have access to any macOS, but hopefully someone else is able to confirm this is a bug (or a feature request).

There is some relevant discussion about this topic at the Light Table forum, for Windows, at least:

This is an issue on the latest version of macOS (10.12.4) at the very least. Discussion on https://github.com/tmux/tmux/issues/475 offers the following code to prevent the error messages: export EVENT_NOKQUEUE=1. Unfortunately, this does nothing to prevent new windows from opening.

Thank you for confirming the issue exists, @jkroes.

@sbauer322 if we replace the last line of the script to the one using open -a ${APP_DIR}/LightTable.app/ --args $@, then the files are always opened in one LightTable instance. Documentation

The problem is, however, that if we use open, then we don't get any stdout to the console. I guess, that the problem, that open command doesn't forward any output, this is why it is not printed out. Still, when -h flag is passed, no LightTable instance is created (as intended, since the process will be killed and help output should be generated). Any suggestions?
