Replacing fullscreen right-click action from drag and page with a context menu with view, zoom, fullscreen, exit

Changing fullscreen page change click area to left/right (top/bottom for single page) section to not be triggered on double click (word selection) or single click in text (text deselection). Therefore also don't disable page change if a text selection exist

Change: Allow word selection from double click in fullscreen mode too

Fix: Remove item instead of showing a disabled Copy context menu item when there is no selection

Adding option to search online for text selection
Removing the behavior that the fullscreen state also set the maximized state because the user might want to retain the non-maximized state in the non-fullscreen state.
Disabling auto-scroll because because it's relatively frequently accidentally activated by scrolling the mouse wheel and has little use
Adding option to hide scrollbars (to increase the page area)
Adding fullscreen toolbar button.
Ading 300% zoom preset
Changed keys: fullscreen (Shift + F11 → F11), presentation (F11 → Shift + F11), quit (Ctrl + Q → Esc)

Adding keys to menu text: Ctrl + C, Ctrl + A
