#471 Code Formatter dict delimiter ":" spaces

[Jari Pennanen]

An option to Code Formatter for dict delimiter ":" to have spaces around it or not.

Choices could be e.g.
With spaces (I prefer this):
{ 'someitem' : 'value' }

Right space:
{ 'someitem': 'value' }

No spaces (I don't know does anyone use this)
{ 'someitem':'value' }
