stinst: Add a pool look-up test for GNUPlot.GNUPlot like conditions.

	* PoolResolutionTests.st: Add TestDefaultPoolResolution>>#testDoubleName
	* STSymTable.st: Add PoolResolution>>#addPoolFirst: and override it
	in ClassicPoolResolution and DefaultPoolResolution.
stinst: Resolve GNUPlot.GNUPlot properly

Importing the Cairo and GNUPlot (probably other packages too) failed
because of GNUPlot.GNUPlot was looked up wrongly in the current
namespace. Add the current Namespace in front of all the other pools.

visualgst: Do not use the TaskQueue for DoIt,DebugIt,PrintIt

Use a separate process instead of the TaskQueue for the DoIt,
PrintIt and DebugIt. This the debugged process will not be
terminated by the taskqueue process.
