Fix MS_Wing chord update on scale.

The previous code assumed that the tip chord of one segment would update
the root chord of the next segment in order to maintain consistency.  This
assumption proved to be false.  Rather than trigger matchWingSects which
depends on the current active section, this fix simply sets both the
root and tip chords.

Bug reported by Bill Fredericks.
Remove classic FUSE component from pull-down menu.

In order to encourage migration to the new FUSE2 component, remove the FUSE
component from the menu of options when adding a new component.

All existing FUSE components will still work as normal.  They can be
modified, copied, pasted, etc.
