[ANN] Magma release 41.2

[Chris Muller]

I have just posted another minor maintenance release for Magma 41
called "41.2" to SqueakMap and the "Magma" project of
squeaksource.com.

Release notes:

- Some low-level optimizations to maUint:at: resulting in better performance.
- Now running MaTimers at userInterruptPriority-1 instead of
userInterruptPriority+1. Afterall, they're only producing application
data, so let's not supercede the real need for userInterruptPriority
processes.
- Improved support for subclasses of Dictionary and Set.
- Fixed performance regression; don't #abort when server #refreshView;
it is only necessary to #refresh, it will improve significantly server
latency when a lot of commits are being performed.
