[LyX/master] Quote filenames used for forward-search with SumatraPDF

[Enrico Forestieri]

commit 6adf079796b7bee280233742878c0754979c6d24
Author: Enrico Forestieri <for...@lyx.org>
Date:   Sun Aug 21 23:33:01 2016 +0200

    Quote filenames used for forward-search with SumatraPDF
    
    Single quotes are special to our parser and must be either escaped or
    quoted if they are part of a filename, otherwise they are stripped out.
    
    See #10342.
