FIX(client, server): Fix patch versions > 255

Previously, the Mumble version was encoded with a uint32
in the network protocol reserving 2 bytes for the major
component and 1 byte for each minor and patch.
The versioning format was changed to include a build
number in the patch field. With a recent update (1.4.274)
the patch field exceeded 255 for the first time and broke
the protocol version.

This commit completely reworks how the version is stored
internally and transfered with the network protocol.
The new version is a uint64 and consists of 4 fields with
2 bytes each. This allows each version component to reach
up to 65535. Furthermore, all instances of integer version
types have been replaced with the alias Version::full_t for
a better abstraction. Version literals have been replaced by
Version::fromComponents calls.

Fixes #5827
