Docstring fix for the NOE assemble_data() method.

The assemble_data() method no longer returns the 'complete' flag.

This is obvious from the missing data list.

The Rx data is now assembled outside of the thread and a message dialog is shown for missing data.

The missing data was previously printed to stdout (the relax controller or shell), but is now shown
in a dialog.

The execute relax button IDs are now all stored.

Created a GUI test for the auto R1 analysis.

This is not complete yet, and is still checking for NOE data.

Created the gui.misc.float_to_gui() function for converting floats to GUI strings.

Fixes for the auto NOE analysis GUI test.

Fix for the get_page_from_name() method - the page is now returned rather than relax data store object.

The analysis page list structure is now private.

Fix for the Analysis_controller.delete_analysis() method for when the last page is deleted.

The gui methods are now called properly and the switch to the previous page is not attempted.
