How to disable automatic spell checking?

Hi Ali,

there's not much to say more, my main language is Czech, having a spellcheck that cannot be turned off is kind of user unfriendly by itself, but even so for item names often containing any web 2/3/4.0 service name which often arent reasonable words in any language.

By the way, why splitting the discussion? prior to that, it was better evident for how many people this is an issue.
