JavaScript debugging (e.g. trace_add() equivalent for JS)

[GoogleCodeExporter]

On the PHP side, Textpattern offers that very useful function 'trace_add'. This 
function allows adding log notes to your code, and since 'trace_add' respects 
the site's production status, those lines can be left in the production code.

For JavaScript there is no normalized debugging tool to speak of, which makes 
debugging of JavaScript more time consuming and harder than PHP. Giving 
JavaScript same type of 'trace' functionality could be very much beneficial.

This would potentially include:

- Feeding JS the site's production status (textpattern.production_status).
- Introducing a 'textpattern.Trace.add()' method.

"textpattern.Console.log('bar');" outputs two lines:

> bar
> undefined

I wonder whether textpattern.Console.log() should return something useful, e.g. 
"this" so one could for instance easily drill into textpattern.Console.history  
from the JS console.

Sorry, I can't replicate double message issue. In which web browser?

Running 'textpattern.Console.log' should print a single instance to the 
console. Before r4657 It didn't print anything else to anywhere else or return 
anything.

I'm not sure what you mean by returning the instance. What .log() returns, 
doesn't affect Console API directly. Neither you can directly feed it it's own 
instance since it would just cause recursion error.

Returning 'this' could be a good idea considering chaining.

Ugh, multi-account login.

I didn't intend to use "for instance" as a reference to any JS object but as an 
English phrase meaning "for example" ;)

r4657 is all I wanted to suggest.
