Added dictionary support

[Bartosz2010]

[PL]
W oknie tekstowym, czasami zdarza się, że "zgubi się" jakaś literka, co może skutkować, że czytany tekst będzie błędny lub niewyraźny.
Dodanie obsługi słowników rozwiązało by ten problem. Podejrzewam, że linux posiada systemowe słowniki, więc nie powinno być większym problemem dodanie takiej funkcjonalności.

Sometimes a letter gets lost in a text window, which may result in the text being read incorrectly or unclearly.
Adding dictionary support would solve this problem. I suspect that Linux has system dictionaries, so adding such functionality should not be a major problem.

Thanks for reporting. You are not the first one who requested this.

I totally agree that a dictionary based spell checker would be very useful and most likely not so hard to implement. I truly want to add this feature, but I keep postponing implementation to the next release because there is always something else to do. What can I say... perhaps in the next release after 4.5. Version 4.5 is practically ready and I don't want to add any new stuff.
