Revision 290956

Added ability to have multiple samples for a module (doc type).
Extra sample choices can be added by adding the sample uri to the modules module.xconf file like so (notice the extra name attribute):

<sample-name>fallback://lenya/modules/xhtml/samples/xhtml.xml</sample-name>
<sample-name name="Two Column Layout">fallback://lenya/modules/xhtml/samples/xhtml-2col.xml</sample-name>
