Revision 1749938

A temporary workaround for "Autocompletion for Compound Widget" - https://issues.apache.org/jira/browse/OFBIZ-7061

Reverts the simple method to use the original schema without namespace. "Duplicates" simple-methods.xsd in simple-methods-ns.xsd as we did, to get the simple-method namespace for compound-widgets.

For myself: when we will do the 3rd more elegant option (no schema duplication), have been changed also:
minilang-catalog.xml
compound-widgets.xsd
