Disable 'open terminal here' menu item for unsaved documents

[hickford]

1. Open Sublime Text
2. File / New File
3. Right click in text editor, 'Open terminal here...'

Expected: Menu item 'Open terminal here' is greyed out (disabled)

What actually happens: You get a popup error "Terminal: No place to open terminal to"

This should be possible via Sublime Text's is_enabled method. Would you be interested in opening a PR adding this feature?

Thanks for the link. The Sublime API is really neat.
