New branch structure

The OpenQBMM repository at GitHub has been reorganized as follows:

1. the master branch is now based on OpenFOAM v1912 instead than OpenFOAM 7 to facilitate synchronization with the sub-module in OpenFOAM from www.openfoam.com
2. the development branch based on OpenFOAM 7 from http://openfoam.org has been renamed development-openfoam.org
3. a new branch development-openfoam.com was added to track developments done on the code targeting the develop branch from the GitLab repository at www.openfoam.com
4. the openfoam.com branch remains synchronized with master and is used to create the git submodule included www.openfoam.com

The immediate impact on users is the following:

• users relying on OpenFOAM 7 can continue using OpenQBMM using the development-openfoam.org branch
• users relying on OpenFOAM v1912 or following can use either the master or development-openfoam.com branch
• user relying on OpenFOAM develop (ESI Gitlab) can use the master and development-openfoam.com branch, or use the git submodule provided directly via the openfoam.com GitLab repository.

Please, report feedback using the GitHub issue tracker.
