Fixes translate(100px, undefinedpx), and transition transform

[atotic]

2 minor bug fixes:

css('translate' ,100) was setting
-moz-translate(100px, undefinedpx),
instead of
-moz-translate(100px, 0px)
causing css asignment to fail.

Problem was strict equality with null. Added check for undefined fixes the bug.

css('transition', 'transform 0.2s') was setting
-moz-transition transform 0.2s
instead of
-moz-transition MozTransform 0.2s
causing transition not to run at all.

Fix is to use prefixed properties as transition arguments.

Love the library! Thanks.

Only my 1st commit fixes the problems. The other 2 should not be part of this patch, and were comitted after the pull request. I am not sure how to remove them.

Hmm—in the first place, css('translate', 100) is not supposed to be valid, and neither shouldcss('translate', [100]). The use of$.cssProps` is rather brilliant though.

I've cherry-picked your relevant commit out—it won't show up here as a merge (because it's not), but your fix should be in there scheduled for 1.0.0. Thanks!
