moved hashing to shellscript to check for posts
removes dependency on sha2 crate and allows users to choose their own hashing algorithm easily. now copies clinte.json to $HOME/.clinte.json once the posts are viewed. a shellscript can be used to compare the hash of the global clinte.json to the hash of the copy. an example script is supplied. on `make install` the example script is installed to /etc/profile.d/, where it will be run for users on login.
