Object mixIn contains 1 line of dead/debugging code

[JamesMGreene]

The current version of Object mixIn, 0.1.1 (2012/01/19), contains a line of dead code (may be useful for debugging, though):
https://github.com/millermedeiros/amd-utils/blob/master/src/object/mixIn.js

Dead code line:
n = arguments.length,

it was probably from an older version (pre amd-utils) and I probably changed the loop structure to use the while(cur = arguments[i++]) and forgot to remove it. thx!
