Replace console.log for lift_defaultLogError - Lift 3.0

We have some a few calls to console.log which should be replace for a custom function that checks if the console function is available client side or not.

See this related thread: https://groups.google.com/d/topic/liftweb/T3BxrGp2xss/discussion

This pull request is for 3.0, because it has a few more calls than 2.6. I'll send a separate one for 2.6
