bugfix: missing support for escape sequences in RainerScript
Only \' was supported. Now the usual set is supported. Note that v5
used \x as escape where x was any character (e.g. "\n" meant "n" and NOT
LF). This also means there is some incompatibility to v5 for well-know
sequences. Better break it now than later.
