Remove expired webkit-gtk2 and webkit-gtk3 ports.

Bump graphics/variety deprecation date, there is a patch for a update which
uses webkit2-gtk3 in ports/236180 but I had issues that I could't fix.

Mark webkit-gtk[23] ports as depricated with the same date as webkit-gtk[23].
Disable webkit-gtk[23] support if the port/plugin supports it.

Remove options for webkit-gtk[23] using ports or if they don't have a
option, mark them deprecated with the same date as webkit-gtk[23].

Haskell and geany where skipped and will be handled by the maintainers.

lang/mono: update to version 5.2.0.215 (and enhance USES=mono)

Highlights:
 - New Roslyn compiler for C# available
 - Improved support for nuget packages in USES=mono

General:
 - fix pkg-plist: mono now produces '.pdb' debug files instead of '.mdb'
 - bump all dependant ports

USES=mono:
 - properly handle caching of nuget packages
 - add support for multiple feeds for nuget packages
 - add support for nuget dependencies in a separate file
 - add support for paket packages

Use USES=pathfix where applicable.

At the moment 1385 ports use BUILD_DEPENDS= ${RUN_DEPENDS} and 450
ports use BUILD_DEPENDS:= ${RUN_DEPENDS}. This patch fixes ports that are
currently broken. This is a temporary measure until we organically stop using
:= or someone(s) spend a lot of time changing all the ports over.

Explicit duplication > := > = and this just moves ports one step to the left

Presenting GNOME 2.28.1 for FreeBSD.  The official release notes for this
release can be found at http://library.gnome.org/misc/release-notes/2.28/ .
Officially, this is mostly a polishing release in preparation for GNOME 3.0
due in about a year.

On the FreeBSD front, though, a lot went into this release.  Major thanks
goes to kwm and avl who did a lot of the porting work for this release.
In particular, kwm brought in Evolution MAPI support for better Microsoft
Exchange integration.  Avl made sure that the new gobject introspection
repository ports were nicely compartmentalized so that large dependencies
aren't brought in wholesale.

But, every GNOME team member (ahze, avl, bland, kwm, mezz, and myself)
contributed to this release.
