Python: Print file:line when editing UI source

GP UI: Make the "Grease Pencil Paper" panel/options part of the Overlays popover

This is a special feature only used during Draw Mode, and functionally
acts like an overlay. Some cleanups/tweaks to this are needed still,
but it's good to get it out of the way.

UI: Dim color of shortcut label in menus and toolbar

The shortcut labels now use the "Item" theme color. Its contrast for hovered
items is a bit low, but not too bad.

Note that this also changes the color of the little toolbar triangle to be grey
(the same color we use for the keymap label). IMHO that looks better though.
This doesn't update any themes other than the default one.

Part of T54711.

Fix ugly half alignment in timeline header.

Splash: add "Alpha" text and link to the development fund.

Sculpting: add Manual detail mode for dynamic topology.

In this mode mesh detail does not change on each stroke, but only when
using flood fill.
