Warn about verbatim string cleanup

[NightProgramming]

There should be a prominent warning somewhere that CodeMaid will clean up any verbatim string, meaning it changes the literal string definition and thus the string value by removing empty lines, removing trailing spaces, etc. I ran into this behavior myself which can be very dangerous potentially.

Thanks for reporting the issue. There is a related issue here: #691

The existing issues deal more with wanting the problem to be fixed I guess. I made this issue here as a reminder that somewhere a disclaimer / warning / info text / whatever, should inform new users about this potential pitfall. Afterwards this issue can be closed while leaving open the other related issues until actually fixed. Thanks!
