Improved the titles of the Sequence and Sequence_2D GUI element for the user functions.

The 'desc_short' user function arg property is now used to create the title rather than the 'name'
value.

The Sequence and Sequence_2D GUI elements can now handle fixed sized sequences.

When the 'dim' Uf_container.add_keyarg() arg is set, then the 'Add' and 'Delete all' buttons are
turned off, the ListCtrl sizes are pre-made, and their SetValue() methods no longer append to the
list. This will allow for better user editing of points, vectors, and matrices.

Converted the 'size' uf arg arg to 'dim'.

The name 'dim' better reflects what this is!

Absorbed the user function arg arg 'dim' into 'size'.

This is only used by one user function, structure.rotate, which has not been converted to the
auto-generation design yet. The size argument is perfectly suitable for specifying the matrix
dimensions.

The Sequence and Sequence_2D wizard page GUI element buttons now have a tooltip.

Alphabetical ordering of the classes.

The paramag user functions are now using the align_tensor icons and wizard graphics.

Converted the paramag.centre user function to the auto-generation design.

The n_state_model user function menus now use icons.

Created a set of basic icons for the N-state model user functions.
