relax version 3.3.8.

This is a minor bugfix release which allows the relax GUI to be used on screens with the low
resolution of 1024x768 pixels.

Resized all fixed-sized GUI wizards to fit on 1024x768 pixel wide displays.

The problem was reported by Lora Picton in the thread starting at
http://thread.gmane.org/gmane.science.nmr.relax.user/1813 .

Both the spin loading wizard of the spin viewer window and the relaxation data loading wizard used
currently in the model-free analysis tab and BMRB export page were fixed. These both had the
y-dimension set to 800 pixels, hence parts of the window would be out of view.

Fix for the viewport <meta> tag for mobile device support.

This is in the SSI head element for all pages at http://www.nmr-relax.com.

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.

Spacing fixes in the CHANGES document.
