Updated default settings for 4.0

- With 4.0 we have a brand new version of Casper, new fixtures and new default settings
- This all comes from the marketing and design teams to refresh the look and feel of Ghost

Note on accent color:

This commit changes the default accent colour again.

The intention is that new sites should get #FF1A75 (pink) as their default.
Any existing sites that do not have an accent colour set yet, should get #15171A (black) on upgrading to 4.0.

These are different as they are different experinces. Fresh sites will be guided to pick a color, so
a bright color is more visible and helps to see what can be done, whilst existing sites get a muted
black, that should be a sensible fall back color.
