Static build year

[joshmoore]

In a follow-on from gh-2173, the year shouldn't be completely dynamic, but rather generated at build time.

Testing in Python:

$ bin/omero shell
In [1]: from omero_version import build_year
In [2]: print build_year
2014

In the web, "© 2007-2014 University of Dundee & Open Microscopy Environment" should be shown.

@will-moore should be happy with the code.

You'll need to add 'build_year' to the context in webgateway/views.py def full_viewer() at:

https://github.com/openmicroscopy/openmicroscopy/blob/develop/components/tools/OmeroWeb/omeroweb/webgateway/views.py#L1669

[joshmoore]

Done.

Good to merge.

This being a rather compact PR and reviewed - can it be merged?
