performance.now and Bitmap class breaking on Safari 5.1.7 on Windows

[anazei]

Besides the usual browsers, I also test my EaselJS work on Safari in Windows but Apple hasn't released a new version of Safari for Windows in years. I'm relegated to using Safari 5.1.7 which is the latest version I could find for Windows. These next two errors only affect Safari 5.1.7 for Windows.

When I use Safari 5.1.7 with your latest builds easeljs-NEXT.min.js and easeljs.min.js (v1.0), I immediate get these errors:

TypeError: 'undefined' is not an object (evaluating 'c.performance.now')

and it appears your Bitmap class has been broken. The Bitmap class still works for me in version 0.8.2 on Safari.

TypeError: 'undefined' is not a constructor (evaluating 'new createjs.Bitmap( "images/paint2.png" )')

The same thing is with safari 7.1 on MacOS (Mavericks). Tested example https://createjs.com/demos/easeljs/spritesheet using https://www.browserstack.com
Demo just does not work with the same error TypeError: 'undefined' is not an object (evaluating 'c.performance.now')

I guess solution is to use some polyfill

Using createjs.1.0.0 also results in "TypeError: 'undefined' is not an object (evaluating 'c.performance.now')"
in Safari 9.1.3 on OS X (10.9.5) and in Safari in iOS 7.1.2.
Of course, using a polyfill for older platforms is a solution, but I am rather surprised that this is not properly covered by the createjs library itself, as it was in earlier versions.

i got error "cannot read property 'now' of undefined" (Line 1401 of createjs.js) when i test on my device (android 2.3).
