[BRLTTY] Updated brltty windows 4.1-2 build

[Samuel Thibault]

Hello,

An updated version of the windows build of brltty 4.1 is available on

http://brl.thefreecat.org/brltty/brltty-win-4.1-2.exe (installer)
http://brl.thefreecat.org/brltty/brltty-win-4.1-2.zip (portable)

This version fixes random crashes and high memory usage which were due
to how Windows allocates window IDs and would often trigger on alt-tab.
