Merge remote-tracking branch 'origin/master' into blender2.8

Fix crash when startup file has an image in it

This fixes an issue introduced in d192d723123add1dde3e9f7e9458aefcafb7e7d2.
When starting up, the UI hasn't been fully initialised yet, and calling
wm_event_do_depsgraph() can trigger icon updates when the startup file
contains an image, causing a segfault due to a not-yet-initialised ghash
for the icons.

Ocean Modifier: removed unused refresh flags

The flags were set and cleared correctly, but nothing was actually reading
them.

Ocean Modifier: removed the MOD_OCEAN_REFRESH_ADD flag

The flag was only used in readfile.c, and resulted in a delayed call to
BKE_ocean_add(); this call is now immediately made instead as it's not
very expensive.
