Improve Zoom controls in Viewer StatusBar:

A

• swap + and – button (similar request)
  most viewers have it +-, but I think this is wrong as they should follow the order of the slider (smallest to largest)

B

• add slider

• replace complex zoom-out/in icons with simple minus (–) and plus (+) symbols

C

• change textbox to editable combobox with all predefined values (including 'Real size') from current 'Zoom' menu

D

• add 3 buttons to switch between zoom manual/auto modes:
  - Lock zoom - manual_locked - remain zoom when switch to prev/next image
  - 1:1 - manual - reset zoom to 100% when switch to prev/next image
  - Auto zoom - auto - depends on settings
  these buttons also work as indicators to see what mode is in use

IMHO default zoom level is something I set once in the options and then never touch again.

If I feel the need to fiddle with the zoom level, I simply use my mouse-wheel.
