I edited the dialogue file and added a whole bunch of lines/edited current ones/removed swear censoring. I made it for personal use, but for anyone wanting more lines or unedited profanity, you're welcome to use it.

Remember to make sure it's a LUA file

(You should probably make a backup of the original dialogue file, just in case mine doesn't work properly or you don't like it)
