WM: rename manipulator to gizmo in Python API

WM: rename manipulator to gizmo internally

WM: rename files, manipulator -> gizmo

Edit doxy files and header guards only.

UI: rename manipulator to gizmo

This is a common, short, distinctive term often used for this purpose.

Changes to internal API's still needed.

GPU_batch: fix error w/ interior line removal

Caused glitch w/ navigation icons showing inner lines.

Keymap: reduce right shift in 2.7x keymap

Keymap: reduce right shift in generated keymaps

Merge branch 'master' into blender2.8

Rename operator property from last commit

Restore operator had same option named differently.

Keymap: option to export all keymaps

Useful to store a snapshot of the current keymap state
so changes to the default keymap are ignored.

Also useful for testing keymap export works properly.

Cleanup: f-string use

Merge branch 'master' into blender2.8

Cleanup: use f-string for addon_utils

Cleanup: minor change for f-string use

Keymap: remove double space in tool-keymap

UI: More descriptive tooltip

VSE: Add image strips with alpha over as blend type

UI: Capital letters for property

Add include missing in release builds

UI: Align Lighting sub-panel of the Shading popover

This better aligns the matcap/hdri browser, rotation/background sliders and
preferences/flip matcap button.

The remaining sub-panels are not perfeclty aligned yet, once the sub-panels
separation is more prominent (and they can be collapsed) we can align those.

Thanks devtalk forum for feedback!
