UI: Icons update.

Updated icon set from Andrzej Ambro?.

- Includes new icons for Top Bar, Status Bar, CD/DVD drives, Home, Documents, Temp, Memory, Options.
- Includes small tweaks to many icons throughout Blender
- Also adds a large CD/DVD drive icon for the file browser

This does not add the new icons in the interface yet.

Fix T70905: Image Editor header hides mask, cache and keyframe info if
flipped to bottom

While flipping the header to bottom works in the MCE (because MCE doesnt
allow overlapping UI) we need to take the regions visible rect into
account for the Image Editor.

Also correct clickable scubbing area (poll for frame_change) in the
Image Editor and the MovieClip Editor not taking UI_DPI_FAC into
account.
