Redundant inclusion of JS/CSS

[mxgrn]

If I have a simple component that extends GridPanel, e.g.,

class ExpandableGridPanel < Netzke::Basepack::GridPanel
js_include Netzke::Core.ext_location.join("examples/ux/
RowExpander.js"),
css_include "#{File.dirname(FILE)}/ajaxrowexpander/
RowExpander.css"

[other stuff here...]
end

and then i create a tab panel, e.g,

<%= netzke :tabs,
:class_name => "Basepack::TabPanel",
:items => [
{:class_name => 'ExpandableGridPanel', :model => 'User'},
{:class_name => 'ExpandableGridPanel', :model =>
'Membership'},
{:class_name => 'ExpandableGridPanel', :model => 'Asset'},
[several more like the above...]
],
%>

Then I get the js and css files included numerous times, once for each
time the class is used.
