Created a GUI memory management debugging script for the align_tensor.init user function.

This repetitively calls the reset, pipe.create and align_tensor.init user functions, and opening the
GUI element for setting alignment tensor elements (the Sequence window). The pympler muppy_log file
shows no memory leaks for these user functions on Linux systems.

Fix for the pipe_control.reset.reset() function when resetting the GUI in non-standard contexts.

This is mainly for debugging scripts when simulating a GUI and hence the GUI reset() method does not
exist.
