sjcl.random.addEntropy():

Browse Source 
* Fixed bug: when data is a number, it is now added to this._pools
* Fixed bug: throws an exception when data is an object but not an array of numbers
* Removed unused variable "ty"

sjcl.random._loadTimeCollector():
* Fixed bug: now passes a number into sjcl.random.addEntropy() instead of an object
