[Laszlo-dev] text attributes problems

[Benjamin Shine]

Discussed herein:
http://jira.openlaszlo.org/jira/browse/LPP-553 : can't setAttribute()  
many text attributes

http://jira.openlaszlo.org/jira/browse/LPP-436 :  fgcolor not  
available for "text" component

CSS users expect lots of control over text properties -- at least  
text color. However, our current support for text color is weird. The  
normal setAttribute("attrname", val) doesn't provide a way to set  
font color; you have to use the special setColor call.

The way to set the text color for an LzText instance is is to call
LzText.setColor(color_as_number);
which looks like this:

LzText.prototype.setColor = function ( c ){
     this.colorstring = "#" + c.toString( 16 );
     this.setFormat();
     this.setText( this.getText() );
}

I can special case text color for the runtime CSS implementation,  
but, yuck! These are marked as fix for seaswirl; any chance this  
could get bumped up so it's in better shape for 3.4?
