copyright dates 'out of date'

@munslowa this is currently the iris pre-release:
http:https://scitools.org.uk/iris/docs/latest/whatsnew/1.4.html

I have updated the build documentation but dont have merge rights.

Should I make changes to the doc. build copyright notices?
SciTools/scitools.org.uk#68

Obviously we cannot make changes to the 1.4 tag release.. so currently our website has a whole host of outdated copyright notices!

True. But we could add it to the 1.4.x branch.
