Don't pass newline characters to bidi algorithm

Browse source 
If you copy-paste a newline character where it's not interpreted, such
as in a level title, the print function wouldn't treat it any special.
font::print_wrap() would, but that's not used here.

However, now that bidi is involved, the newline is passed straight to
SheenBidi which interprets it as a new line (which would need a new
SBLine to be created, or maybe even a new SBParagraph if there's two).
All while we're still treating it as a single line. This means the text
would just stop being displayed after the first newline. This is now
fixed by treating all newlines as spaces.
