Re: Auto detection of grammar

I eventually did it this way: if a schemaLocation (or noNamespaceSchemaLocation) is detected in the document root element, then it is proposed as the default schema in the configuration panel. I also added the default selection of the "Ok" button, so that the user only has to type "Enter" on keyboard. However the config dialog is still proposed to allow any other configuration.

I assume here that the schema instance namespace is always "xsi", which is the common usage (if it's not, schema location will be ignored).

Then, in Pollo.createEditorPanel() method:
        if (viewTypesDialog.showDialog(polloFrame))
becomes:
        if (viewTypesDialog.showDialog(polloFrame, xmlModel))

I guess this could be helpfull to other pollo users.
