How to make text in lowercase?

PLUGIN: Badwords

================

Kicks player when they use bad words defined in config/plugins/badwords.lst more

that X-Times

Добавления от jTommy:

1. В причине бана/кика указывается плохое слово (удобно при просмотре логов, особенно при использовании плагина logkickbans) .

2. Теперь плагин не ищет плохие слова внутри слов. Например, выражение "4 рубля" теперь не будет считаться плохим.
