remove CR/LF symbols form the parsed strings

Attention

it is a bit dangerous operation The operation allows to write "very long" input strings for opts-files (it is actual e.g. for DataOnDemandSvc configuration) by splitting the strings into few lines All new-line symbols (as well as '
', '', CR/LF etc are substituted by ordinary blanks.
