Upgrade PHPMyAdmin to latest 4.6.4

[TGates71]

There are some issues with this.
Some OS distributions have a lower minimal PHP/MySQL version that the current phpmyadmin will not run on. For those using PHP 5.5.0 or newer AND MySQL 5.5 or newer/MariaDB 5.5 or newer may use the 'phpmyadmin-au' module which will auto-update it to latest version.

For users on older distributions, they will need to remain on an older version.

[amaisonneuve]

Agreed, but as a go forward strategy we should increase the minimum requirements for future versions to 5.5 for both PHP and MySQL/MariaDB. No?

[TGates71]

Correct. This is already planned as we update the code and installers for newer OS versions.

[MBlagui]

We should instead install different phpmyadmin depending on OS/ PHP installed.
I can be done.
