[ANN] Magma release 41.1

[Chris Muller]

I have just posted release 41.1 of Magma to both squeakmap and the
"Magma" project of squeaksource.

There is no new functionality, but 41.1 contains some important
factorings and improvements in preparation for release 42.  There are
also some important fixes to a couple of unfortunate bugs that crept
into release 41.

I recommend anyone using 41 to upgrade to 41.1.
