Update x11/kdelibs4 to 4.14.30.

This is the latest stable release, and contains many of the patches we kept in
files/. The exception is patch-mimetypes_kde.xml, which just did not seem
necessary any longer: area51 r8180 mentions it was working around issues in
shared-mime-info, which has since been updated. While here, add several
dependencies that were reported by Poudriere's checks.

Bump PORTREVISION in ports that use %%KDE4_KDELIBS_VERSION%% in pkg-plist.
