UV Project and UV Warp panel layouts

Miscellaneous cleanup

Generalize recreate panel lists, add functionality

The recreate panel list concept should be MUCH easier to use
in different situations, as now it makes use of callbacks for any
modifier-specific functionality.

This commit also enables storing the panel expansion in modifiers
so it is remembered even when the panels are replaced.

Use 2.8-compliant layouts for some modifiers

Add apply / copy buttons

They're not working yet, but it's one possibility for
the location of these buttons.

Also make the order of statements in the panel_draw
functions more consistent.

Add settings recently added to modifiers, tweak UI

Re-order modifier mode settings for right align

Merge branch 'master' into modifier-panels-ui

Cleanup: Remove print statements and comment

Drag and drop modifiers from panels

When the panel animation finishes, a new move modifier to index
operator is called, reordering the modifier stack. Then on the next
draw, the panel types mismatch and the stack is redrawn (or new
indices are set if the types match).

Don't lower the active modifier index past 0

Fix panel header drawing

- Use the preset callback to draw the modifier mode buttons.
- Don't draw empty panel label strings.

Add modifier move to index API function

Small tweaks to modifier panels
