Replace spellchecker with new multi-language spellchecker
Currently built-in spellchecker supports only English and is also a proprietary one (as far as i know). Cstux has created a spellchecker plugin which has support for multiple languages (currently English and German languages are built-in). Though i wonder about the license to use those languages. Probably there are some free available spellchecking dic files.
fix npe on spark shutdown
now support country languages like de_AT or ca_ES
0.3 version has 3 dicts (English, German, Spanish). The dicts are taken from OpenOffice.org project. Also It can be disabled in Preferences (separate options group after the Notifications) and Auto-spelling can be turned on/off.
After this new plugin will be placed in place of the old one "Perform spellchecking in background" should be removed in Preferences > Chat window.
