Added useful filters for input parameters:
  "AbsolutePath":
     That from a parameter value like this: ~/test/a/b/c.txt figures out the the absolute path /home/slavey/a/b/c.txt. Plus works correct in phar context.
     Example:
           <bin> fetch-all --output=~/comics/matthew/

  "ArrayString":
     That from a parameter with value like:
     a) (complex) HTTP query string (example: a=1&b[1]=3)
     b) simple comma separated string: (one, two, three, x)
     Example:
         <bin> fetch --comic=superman,mickeymouse,spiderman,dilbert,you-name-it
