Change padding around checkboxes

Two changes:
* Reduce padding between checkbox and text. That makes it clearer what
the checkbox belongs to if there's also a column heading in front of
the checkbox.
* Don't add padding on the left side of checkboxes. That makes them line
up better with items above and below it.

Fix error in previous commit

I unintentionally changed the size of checkboxes, should be back to the
old size now.

Logging: log warnings which had been disabled since 2.4x

Use new layout features throughout all Cycles properties

Better alignment in Experimental Preferences

Use checkbox+value for Sculpt Plane Trim & fix column headers

UI: Tweaks to modifier layouts

- Use checkbox + values configuration and expand 3-axis enums.

Various small tweaks to modifier layouts

Merge branch 'master' into modifier-panels-ui

Merge branch 'master' into modifier-panels-ui

Simplify Edge Split Modifier Layout

Rename RECREATE panels to LIST panels

Use layout row with heading

Also use the new uiItemR flag to clear decorators

Add new options to solidify modifier

The subpanel organization might need to be rethought here, some of the
new items don't fit perfectly into the categories.

Merge branch 'master' into modifier-panels-ui

Add margin and rounded corners to list panels

This helps differentiate them from regular panels and makes it clearer
that they are separate from each other.

Also added a list panel subpanel flag to avoid always searching parents to
see if a panel belongs to a list panel.

Use PNL_ prefix for new panel type flags

This prefix should be changed, but it's best to be consistent for now

Tweaks to layout for many modifiers

Bevel: Move to two new panels
Data Transfer: Add advanced panel for rarely used inputs
Mesh Sequence Cache: Don't use useless subpanels
Mirror: Clip in main panel, data panel instead of UVs
Multires: Advanced panel and add missing properties
Normal Edit: Offset in subpanel
Simple Deform: Orientation panel to restrictions panel
Solidify: Add normals subpanel
Subdivision Surface: Add advanced subpanel
UVWarp: Add transform subpanel
Wave: use_x and use_y as toggles on the same row
Wireframe: Don't use split layout

Option to insert blank dummy decorator for uiItemFullR

When there are multiple items in a property split row (e.g. mirror axes
in the mirror modifier) the decorator would only apply to the first
element. A dummy decorator could be inserted manually by using
`uiItemL_respect_property_split()`, but it's better to let the UI code
have an option for that, the case is common enough.
