Message:

UKMO dev_r5518_GO6_package branch: update to tracer trends diagnostics. Corresponds to update at revision 8102 in 3.6_stable branch.

1. Correct bugs in calculation of total trends and trends due to vertical diffusion.
2. Output component trends every second timestep so that sum of component trends plus Asselin filter trend equals total trend.
3. Layer-integrated versions of trends (as per CMIP6 definition) available in field_def.xml.
