lang/mono: update to 4.6.1.5.

USES=mono: add nuget argument
  The nuget argument adds support for nuget packages.  The nuget
  packages must be specified in the NUGET_DEPENDS variable.

devel/monodevelop: update to 6.1.1.15
 - Switch to github.  The other official source is quite a few versions
   behind.
 - Add missing dependencies (fsharp, ssl2, curl)
 - Add required nuget packages
 - Add required external repositories
 - Drop options.  Although ./configure offers these flags, there is no
   functional change (i.e. no-op)
 - All patches have been upstreamed (and the one we need is from
   upstream).

lang/fsharp: update to 4.0.1.15
 - convert to use the nuget argument.

 ChangeLog:
   - Fix null condition in Fsc task

lang/mono-devel: update to 4.6
 - switch to new test target (currently tests the port to be installed)

www/gecko-sharp20: depreciate: broken and no-upstream
 - Give 1 month for anyone to complain that this port is being removed.

x11-toolkits/gtk-sharp30: bump PORTREVISION
 - Add LICENSE information
 - Add missing dependencies (per stage-qa)

x11-toolkits/gtk-sharp20: update to 2.12.40.
 - Add LICENSE information
 - Add missing dependencies (per stage-qa)
 - Change download location per Mono's Gtk# website.
