Make use of a private API to prevent Slate from hanging waiting for
unresponsive apps.

Tested by pausing Google Chrome with a command like `kill -STOP 11019`,
then interacting with Slate (using hot keys to reposition windows). I
observed that there is some lag before the `CGSEventIsAppUnresponsive`
API actually registers the state of the world; it returns `false` at
first, but after about 20 seconds it correctly returns `true`. During
the initial interval, interacting with Slate is laggy; after that, it
becomes snappy.

Resumed Chrome with `kill -CONT 11019`.

Fixes: jigish#140

Thanks to @sdegutis for the tip.

All good sentences deserve a full stop.

…s allows creating multiple named snapshots (example config at https://github.com/ayn/dotfiles/blob/master/slate.js)

This can be useful to distinguish between apps like Chrome and Chrome
Canary (which both report their name as "Google Chrome" but have bundle
identifiers `com.google.Chrome` and `com.google.Chrome.canary`
respectively).

This can be used in a `.slate.js` to do things like the following,
which is a layout that pushes Canary windows to the left half of the
screen and normal Chrome windows to the right half:

    slate.layout('my-layout', {
      'Google Chrome': {
        operations: [function(window) {
          var app = window.app();
          if (app.bundleIdentifier() === 'com.google.Chrome.canary') {
            // code to push window left
          } else {
            // code to push window right
          }
        }],
        repeat: true,
      },
    });

Including a description for how to turn on the Accessibility API for OS X 10.9 Mavericks.

…local variable causes Slate to crash if window hints is triggered in certain contexts (Emacs.app visible or Calendar.app visible).

Removed the overriding of the architectures and turned on some
additional warnings it recommended.

specifically, if AXUIElementCopyElementAtPosition returns an accessibility element that doesn't have the window role or attribute, return it anyway.
