Spell checking with multiple dictionaries #536
Description
Hello! Retext is very functional and minimalistic editor, I like it and I use it every day, thank you very much for development!
The only one feature I'd like to add: is it possible to use multiple dictionaries in spell checking (ru_RU + en_EN for example)? As I know It's possible to create multiple pyenchant spell checkers or merge dictionaries in /usr/share/hunspell (IMHO second way is too inconvenient). Could you implement ability to set multiple dictionaries in GUI? (Somethig like "ru_RU,en_EN")
