"execute" directive in the "*.sublime-project"

Found myself doing some repetitive actions:

$ subl --project project.sublime-project

$ chrome 127.0.0.1:8882

$ grunt watch

And that's every time I'm opening a project.  Would like to put 2 last commands into project.sublime-project file so that Sublime would do it for me. And since watch is a persistent operation, I'm fine with that I have no control over it while project is open.
