Changing fullscreen right-click action from drag and page change to 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)

Related change: Don't disable page change if a text selection exist

Related 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

it's sometimes accidentally activated by scrolling the mouse wheel

it has little meaning
