Generates a file containing file hashes, copies files with md5 as part of the name, partial updates of hashmap possible.


This grunt task iterates over its source files, calculating the MD5 hash of each, then creates a file containing the list of filenames and hashes. It can also create a copy of original filename with hash as part of the name and works with pre-existing hashmap files extending them so partial updates are possible.
