Fixes newline characters not creating new lines

[rapterjet2004]

• fixes New lines removed from message #3335

Basically, replaced every "\n" with "\s\s\n" before processing. No idea why that works, but it does for some reason.

No idea why that works, but it does for some reason.

because in markdown for code-style one would add a line-break after each sentence (within a paragraph). However since it is a paragraph the line-break would not be rendered, so when you add 2 spaces (since after a sentence there would only be 1 space) this formatting rule doesn't apply anymore and the line-break gets rendered. :)
