Consider exporting parameters without prefix

Current Situation

• Some parameters in exported .ini files have to be used without parameters:
  • overwrite_files
  • ...
• Instead, the XML Editor always provides a prefix for a parameter

Desired Behavior

• No prefix is used for parameters that are specified in the XSD schema accordingly
  • overwrite_files
  • ...
• The respective XSD schema setting is provided with the appinfo element and the FlatParameter attribute suppress_prefix like this:

  		<xs:annotation>
  			<xs:appinfo>
  				<FlatParameter name="polling_server" suppress_prefix="true"/>
  				<FlatParameter name="PollingServer" suppress_prefix="true"/>
  			</xs:appinfo>
  		</xs:annotation>
