Allow specification of start hour

NEMO is hard-wired to always start a run at the start of the day (at 0z). I propose to extend the option of setting the start date to allow for the setting of a start hour via a namelist option.

#1310: Create a new branch for allowing arbitrary start hours in NEMO rather than just 00:00.

There is a related ticket at #1037 which can start NEMO at a different start time by changing the initial time step (I believe).

I've attached a version of daymod.F90 relative to NEMO 3.2 with the changes for our method which involves setting at start hour using nn_time0.

Update to the code to allow restartability for runs of less than one day. This was tested by modifying the AMM12 and ORCA2LIM3 SETTE tests. I've also made a small update to the SETTE test to retain the flexibility to run those tests with different run lengths. Updated diff (after the trunk merge)
