[Opm] OPM release 2016.04 first release candidate

[Atgeirr Rasmussen]

Dear OPM community,

The first release candidate is ready for the 2016.04 release can be tested!

There are major structural changes compared to the last release:
- opm-autodiff has been renamed opm-simulators
- opm-polymer is no longer an independent module, it is now part of opm-simulators
- dune-cornerpoint has been renamed opm-grid
- opm-porsol is no longer an independent module, it is now part of opm-upscaling
- opm-output is a new module, required for opm-simulators
- opm-verteq is no longer actively maintained (its code repository will remain available)
The module page on the web site shows the current structure: http://opm-project.org/?page_id=274

There are binary packages available for 64-bit Ubuntu 14.04 and RHEL 6, also there is experimental support for Ubuntu 16.04. For those building from source, the relevant branch is called release/2016.04 in each repository.

For Ubuntu, note that the binary packages are not in the usual (ppa:opm/ppa) archive but in ppa:opm/testing. To install (for example) Flow from opm-simulators, you should do the following:

sudo apt-add-repository ppa:opm/testing
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install libopm-simulators-bin
