modify spell check to use pspell or a web service.

[George M. Harkin]

Currently FCKeditor uses aspell with an exec call to perform spell checking operations.

For security reasons, many sites have exec calls disabled. It would be nice to offer different spell check options.

• aspell (exec)
• pspell (language dependent)
• web api (google spellcheck).

[Frederico Caldeira Knabben]

We should be working on this for the new spell checker. We'll consider your ideas during the analysis, thanks.
