Fix for the updating of analysis tabs with the deletion of data pipes.

The delete_analysis() method now decreases the _num_analyses and _current values at the very start.

The current page index is changed if a page before it is deleted.

This is to remove a GUI bug.

Analysis tabs are now removed if the associated data pipe is deleted.

This avoids nasty GUI crashing.

Reverted r14590 as GetStringSelection() is not how the value from the combo box should be read.

The command used was:
svn merge -r14590:r14589 .

The GetStringSelection() call was causing weirdness if 'Apply' is clicked twice.

Fixes and improvements for the peak list wizards in the NOE and Rx auto-analyses.

The integration points page is now correctly set up. And the spectrum ID is now only set if the
field is blank, preventing a reversion of the user selected value.

The parent of the Question dialog in the pipe editor window is set so the window doesn't disappear.

Without this, the main GUI window comes to the front after the dialog is shown.

Fixes for the pop up menu in the data pipe editor window.

The parent window is now correctly set, so the menu entries are now functional.

Improvements to the showing of the relax controller on errors and warnings.

The Show() call is no longer made if already shown, and if not shown, the LogCtrl is scrolled to the
position of the error message.

Fixes for the main GUI window moving in front of the spin viewer window.

The spin viewer window is now set as the parent for the Question dialogs, so that this window
remains at the front.

Fixes for the residue user function GUI pages for when default values are sent to the page.

This fixes the user functions in the spin viewer window.
