[Chameleon] hiding annotation layers in the legend

[Paul Spencer]

Ken,

the problem is that the LegendTemplate widget is a bit dumb about 
layers, it assumes that if it doesn't see a layer in the form variables 
when the page is submitted, it should be turned off.

The best way to accomodate this is to actually use opt_flags=15 and use 
the layer type or metadata to hide it through using [if] flags in the 
template.  Layers that should be displayed go in one if and hidden 
layers go in another if

To get hidden layers to stay on, output

<input type="text" name="legendlayernames[]" value="[leg_layer_name]">

inside the if for hidden layers.

Cheers

Paul
