#50 Change setTimeout/setInterval to use funcs, not strings

[brettz9]

Hi,
Although you may be using it securely, since I added EditArea as part of my Firefox extension, and they review extensions there, flagging those which use setTimeout/setInterval or other eval-like functions, I was concerned some reviewer might object to this, or at least possibly delay the review process if the calls were as strings rather than functions. It might add peace of mind to others too. Would you accept a patch which changed from strings to functions? Since there are quite a few instances, I wanted to check first... Thanks...
