Update Warning-strings to use a standard-format

- ensure warnings always start with "Warning:" and that the first
  character after ":" is written uppercase
- ensure the first sentence in warnings ends with an "!"
- remove unneeded spaces from Warning-strings
- add missing Warning-string translation
- remove a "\n" and replace with untranslatable "<br><br>"
