Subject: changing the second parameter in directory_map to an integer that
controls recursion depth.
A depth of 0 is fully recursive to maintain backward compatibility with the boolean values.

Deprecated the dohash() function in favour of do_hash() for naming consistency.
Non-backwards compatible change made to get_dir_file_info() in the File Helper. No longer recurses
by default so as to encourage responsible use (this function can cause server performance issues when used without caution).
+ Modified the second parameter of directory_map() in the Directory Helper to accept an integer to specify recursion depth.

you may set a third parameter to true (boolean):
