Fixing errors on reading files with compound names

Because if you try to read "something something.pdf" you would end up with command like `java -server -Djava.awt.headless=true -jar tika-app-0.10.jar something something.pdf` which raises an error, the fix is to use the path to file enclosed in "'s and include protocol like this  `java -server -Djava.awt.headless=true -jar tika-app-0.10.jar 'file://something something.pdf'`
