The alias list now displays the user model (multiple aliases *of*
a root part, rather than a collection of names *including* the
root part). This simplified the error detection logic, fixing
the first bug in the bug report.
Updating the part in the library is now done uniformly on OK
(which was the second bug in the bug report).
