[Docutils-develop] languages; all keys lowercase...

[Bill B. <bb...@co...>]

To make a document more readable in raw form, I naturally used :Author: 
as opposed to :author:.

The document failed to parse, as a result.

Looking at the implementation, is there any reason not to use lower() 
when looking up a name in the Languages dictionary/module?

I.e.:

     def visit_admonition(self, node, name):
         self.bodyContent.append('<hr width="50%" />')
         self.bodyContent.append('<b>' + 
self.language.labels[name.lower()] + ':</b><br />\n')
