#2466 spell check not working within beamer-\note{}-Tags

[Anonymous]

..as the title says: There is no spell checking done on all text which are enclosed within any \note{}-environments.

These environments are e.g. used as presentation notes on a second screen when using the beamer-class and I would find spell checking to be quite useful even if only the presenter gets to read those notes.

Tested in version 2.12.22
