[Seaside] Seaside updater

[Richard K Eng]

I looked at the SUFormTest code. It took me into the guts of WARenderCanvas 
and WARenderContext where I got totally lost. All this stuff about 'context' 
and 'nextKey' and so on is so convoluted. For anyone but a Seaside expert, 
this would be unfathomably difficult to use without clear documentation and 
simple examples.

A few HowTo's at seaside.st would be very helpful for the rest of us... How 
To use #updater, for example (since #updater is a major aspect of Seaside 
programming).

Thanks,
Richard

Please, read the comment in SUAjax of #triggerForm: and 
#triggerFormElement:.

Also check out the example in SUFormTest.
