Update menu for OME 5 to docs pages & update version history (rebased onto dev_4_4)



This is the same as gh-538 but rebased onto dev_4_4.

----

This PR adds to the doc menu ready for the OME 5 doc releases and also updates the BF version history file which I'd forgotten about this year.

Can be back ported to dev_4_4 once we are ready to release the docs.
