Created the UF_base.get_title() method for setting wizard window titles.

The deselect.all() user function now uses this.

Removed the UF_base.setup() method as nothing is using it.

Updated all of the select and deselect user function documentation to be suitable for all UIs.

The 'change_all' flag in the select.read user function window is now also set to False.

This is the 'spin identification' to 'spin ID' change!

The previous commit was changing the default value of the 'change_all' flag in the deselect.read
user function window to False.

The spin_id_element() text is now 'The spin ID string'.

The user function windows now use _doc_title_short for the titles.

If this doesn't exist, it falls back to _doc_title.

Created a short title for the structure.load_spins() user function under load_spins._doc_title_short.

This will be used in the GUI and other parts of relax.

The wizard is now a frame rather than dialog, as this gives better focus properties.

Shifted the spin system GUI element for the analysis pages into the base class.

This will be used throughout the different analyses.
