William Reynish 7fc60bff14 UI: Layout changes for new checkbox layout possibilities 
Follow-up to previous commit.

Some examples:
{F8473507} {F8473508} {F8473509} {F8473510}
For more screenshots, please see D7430.

We use column or row headings here to bring more structure, and to give
the eye visual anchors which aid eye-scanning. The left-aligned
checkboxes likewise help with this. And we keep the adherence to the
center line, so the alignment matches up between the various buttons and
controls.

* Changes the property split percentage from 50/50% to 40/60%. This is
  needed to give enough space for the checkboxes. But in most cases this
  looks better anyway - see Transform panel. In some cases it simply
  fills out the available space more efficently.
* Fix various hacks where we previously used manually defined splits.
  When we did this, the alignment was never quite right, and the layout
  code was a mess.
* Adds column headings to many places where a list of checkboxes all
  share a common purpose or leading text.
* Add checkbox + value configurations various places where a checkbox
  only serves to enable the value slider
* Removes most uses of grid flow layout. The grid flow layouts combine
  poorly with column headings, and also they would mess alignment up
  badly. The grid flow layouts also often made buttons and controls jump
  around on the screen if you would just resize editors slightly,
  causing visual confusion, making users lose their place. The logic for
  at what time the list of items would re-flow was often flawed, jumping
  to multiple columns too fast or too late - and frankly, the grid flow
  layouts would often just look bad.
