lang/mono Updated to Mono v4.0.1

[Anders Jensen-Waud]

Hi all,

As part of our effort to port CoreCLR and the Roslyn compiler collection to
FreeBSD, it has been necessary for us to have a working version of Mono
v4.0.1 on FreeBSD.

The version in Ports is on version 3.x, which is getting quite old. So I
updated the port Makefile to 4.0.1.28, the most recent available version
from the Mono team.

The patch is available from here:

https://github.com/ajensenwaud/mono4-freebsd-ports/tree/master/mono

Given that this is an update to an existing ports infrastructure, would you
still like an shar file submitted to the list? Or do you prefer a separate
patchset?

Cheers

Anders
