Better hash function for Guacamole user password
!335 (merged) introduces Guacamole support, and with it, the Guacamole password is encoded using MD5 in a config file (the only hash function that Guacamole currently supports with the authentication scheme we're using). We might be able to use a stronger hash function if we move to database authentication: https://sourceforge.net/p/guacamole/discussion/1110834/thread/0e8d9291/
Maybe with a salt???
