Use the semantic versioning and add a version header file

[kloudkl]

Recently released versions are called 0.9, 0.99 and 0.999. Another popular method to set the number is the semantic versioning. Even HBase, one of the Hadoop ecosystem projects, that has been approaching version 1.0 for a long time names its recent versions as 0.9x.x.

OpenCV updates its version in a header file for the users to know the current version they are using. It also enables CMake to automatically version some other files.

Semantic versioning is a nice scheme, but it has too much overhead at least until 1.0. A version header is a good idea too, but likewise the bookkeeping is a little bit of a hassle.

Nice ideas for the future all the same!

Keeping open to remind us of the version header.

Caffe now declares a version, but we haven't followed semantic versioning practices. Closing as close enough for now.
