Initial port of FBX to 2.8.

Default cube scene exports and imports ok (besides missing features like
nodal material handling). Anything else is either known broken, or yet
to be tested. :P

Note that I raised main number of addon version, so that we can keep
track of smaller fixes that can be done in both 2.7x and 2.8 versions of
the addon.
