event: minor simplification

event: fix calls to main next_page

remove a bunch of unused imports

rework page change code

- remove next/prev code from image handler
- move logic to main, and simplify
- add main.page_changed callback, to be used instead of main.draw_image
(not a callback anymore): will trigger on page change (while
draw_image would trigger each time the page was being drawn)

fix cursor auto-hiding when a modal dialog is active

Fix [bugs:#73]: make sure we receive *all* mouse motion events.

CTRL+mouse wheel zooms in/out.

Fixed single page stepping in double-page mode for hotkeys.

This functionality has been broken for a while (since hotkey
modifiers have been fixed) and has now been introduced as new,
configurable hotkey.

Some unused imports and variables removed.

Split scrolling.py (Refactoring)

- Split scrolling.py into scrolling.py, layout.py and box.py.
- Move constants in scrolling.py to constants.py

Scrolling bug fix and refactoring

- When loading a new page in double page mode, the viewport now automatically
moves to the actual page rather than just the corner next to it.
- MainWindow.scroll_to_fixed replaced with scroll_to_predefined.
