Increase sleep time on macos before running copy and paste commands

[jmhammond]

I want to follow up on the closed issue #4 because I'm still having the original documented behavior - sometimes Emacs includes its clipboard text, other times it gets the selected text.

When I changed this line to have 0.1 second delay:

        (sleep-for 0.1) 

it works every time. Apparently I need just a little more time to propogate the clipboard - I bet emacs-everywhere loads too fast (it's pretty instantaneous. I love it!).

Is this something I should keep patching in my own custom version or would it be beneficial to share as a PR?

Thanks for the issue, and sorry for the delay. I'm not sure if I should just tweak the hard-coded value or make this customisable. Would you mind testing 0.01-0.09 so I can get a better idea of how this behaves?
