Webmin 1.830 released

Howdy all,

I've rolled Webmin 1.830 out for all Virtualmin repos.

Changes since 1.821:

• Numerous bugfixes across multiple modules.
• Support for systems that have a different local and remote MySQL version.
• Major update to the Authentic theme.
• Support for the latest LDAP client configs as seen on CentOS 7.
• Removed two ancient obsolete themes from the default package.
• File Manager updates to support SElinux and file attributes.
• Support for the latest Let's Encrypt client program and CA certificate.
• Translation updates.

As always, if you find any bugs, file a ticket in the tracker.

Cheers,

Joe
