Title: Add zoom actions to View menu

This commit adds 3 actions to the View menu, as well as shortcut keys
for them:
- Zoom In (ctrl-+)
- Zoom Out (ctrl--)
- Normal Size (ctrl-0)

The former two are useful if the user does not have a mouse wheel.
The last one is useful if the user wants to quickly restore the default
zoom level.
