Officially require Qt 4.8 or newer

Since v2.3.0rc0-1002-g1cd2255, Qt 4.8 became mandatory, reflect this in
the version requirements. This will not affect a lot of distributions
(RHEL and SLES only had Qt 4.6).

For a more complete list of supported platforms, see
https://wiki.wireshark.org/Development/Support_library_version_tracking

While at it, correct some other minimum versions in documentation.
