Review request for kdelibs and Plasma.

Description
-------

Krunner's spellcheck plugin has been pretty broken since \
bd291d21f096a714a171e7af3a534ba345ca5659 (about two years ago) because it called \
Sonnet::Speller::setLanguage every time the spellchecker was invoked, which was (very \
much) not thread-safe.

This patch makes Sonnet::Speller::setLanguage threadsafe by protecting all access to \
the internal dict pointer using QReadWriteLock. 

A related review request is 106244, which adds more fixes to the spellcheck feature.

This addresses bugs 264779 and 303831.

Testing
-------

Compiled, installed, used for a week or so, spellchecked a bunch of things.

Thanks,
