add the encrypt (bool) flag to the config files
fixed a potential bug, we now check if the content directory exists before enumerating it
performed composer update
brought in Encryption class, use encrypt flag to decide if we encrypt file contents, encrypt/decrypt works for new pages and loading pages
Merge branch 'master' of github.com:stephcook22/chula

Steph has including editing of pages, I had been working on encryption, therefore it now requires a merge :)
