Update DigiKam and related ports to 4.14.0.

This is a huge leap, as we are moving from 4.2.0 (released in August 2014) to
4.14.0 (released in October 2015). Version 4.14.0 is the last KDE4-based
release, and 5.0.0 will be based on KDE Frameworks 5.

Noteworthy port changes:

• Most patches in graphics/digikam-kde4 are no longer necessary.
• graphics/kipi-plugin-googledrive and graphics/kipi-plugin-picasaweb have been merged into graphics/kipi-plugin-googleservices following what upstream did to those plugins.
• astro/libkgeomap and graphics/libkface are no longer included in the DigiKam tarball and are now completely independent ports whose tarballs are released as part of KDE Applications.
• net/libmediawiki is neither included in the DigiKam tarball nor released as a separate tarball, so we had to resort to fetching it from an older DigiKam release which contains it.
• graphics/digikam-kde4 now has a runtime dependency on x11/kde4-runtime. See bug 203222 for details.

A lot of people have contributed to this update over the years in our
experimental area51 repository. Tobias Berner (our usual suspect), Adriaan
de Groot, makc@, alonso@ and jhale@ at the very least.
