Implementing password hashing

[kimslor]

Description

A password hashing method was created in the user models. This method has been used to hash the plain text password provided by the user during account creation. Now the hashedPassword will be stored in the DB and not the plaintext password. This hashPassword() method should be used for password verification, such as login.

salted-md5 was used for the hashing of the plaintext password.

41 tests failed! I have rerun the CI as it is very likley the CI tests failed because of commit(s) made before testing from prior commit(s) has completed causing a clash between test suites executing and accessing the same resources in parallel. I will wait until the final commit has been made and all CI tests are passing before I review again.

Now 31 tests are failing. Let me know when this is ready for review again, please.

I don't know how it happened but I seem to have mistakenly labelled this already merged pull request as invalid. It is not invalid. I have removed the label and moved the pull request back the Done column. I must have had too many tabs open at once.
