add URI attribute to plugin doctype definition

The build-in document types use catalog contributions to map public or
system id's to the dtd file. In plugin projects, the user defined
document types had to use the file name as system id to be resolved.
This commit adds an additional 'uri' attribute to the plugin config to
config the file name independently.
