[AgileWiki] RowRolon now has a custom display

[Bill la F. <bil...@su...>]

This morning I did a bit of refactoring of TableRolon.docEvent, breaking 
out a getColumns method.

I then added a getTable method on RowRolon.

Finally, I wrote a docEvent method on RowRolon. This custom display 
produces a 3-column table:
Column name,
value and
description.

I must say, it is a lot nicer than just a blank display. I want to 
continue to work on rows a bit, adding a command to add a row to a table 
and also a command to edit a row. After that it would be nice to add 
commands for creating descriptor units and table descriptor units.

Meanwhile, on my day job I've been having fun writing an xml-driven 
GUI-independent wizard engine. Its nearly done. The next step would be 
to wrap a GUI around it, but the trick there is to make it look like the 
product it is replacing. :-( At some point I also want to add wizards to 
AgileWiki, though right now it has enough half-finished (and 
half-baked?) features. I'd rather work on closure.
