default "log" function

[psd]

authors can't rely upon console.log existing in each browser, so typically endup writing a per-plugin "log" function to detect if the console exists before calling console.log, or displayMessage.

suggest the core provides a dummy log() function with the same arguments as console.log, e.g in main.js:

log = function() {};

Extensions can then include calls to log() without causing problems in IE or doing anything, by default.

A TiddlyWiki author can select which variety of logging they prefer, by including a plugin which redefines log, e.g.:

 http://svn.tiddlywiki.org/Trunk/contributors/PaulDowney/plugins/LogMessagePlugin/

which optionally calls console.log, displayMessage or writes text to a popup window.
