Fix for the GUI status bar element widths.

Fixed widths in pixels causes text truncation on many systems, depending on the width of the main
relax window. Instead variable widths should be used to allow wxPython to more elegantly present
the text while minimising truncation.

Updated the frame order auto-analysis for the time -> system.time user function change.

When the userfunction script() is called, a notification of pipe_alteration is made.

This will force the GUI to update, and make sure that it is up to-date.

Optimising the width of the statusbar.

Added a newline character after printing the script.

Fix for GUI prompt bug, where ansi escape characters should not be printed when interpreter is inhereted from wxPython.

Changin the Keyboard shortcut for Changing the working directory to Ctrl+W. Since Ctrl+C is often used for copying (from the terminal).

For the 4 autoanalysis methods, the default results directory is now the current working directory instead of the lauch directory.

gui/analyses/auto_noe.py
gui/analyses/auto_relax_disp.py

Updating the self.system_cwd_path when a directory change is observed.

Letting the current working directory be printed in the statusbar in the bottom.
