Refactor scrollbar into its own file (#1124)
* Move scrollbar to its own file * Don't call `Scrollbar` functions if `View` is not scrollable * Allow horizontal scrolling in `Scrollbar` * Add horizontal scrollbar to `View` * Add `root:horizontal-scroll` command with `shift+wheel` keymap * Prioritize vertical scrollbar hover * Don't send mouse movement to vertical scrollbar when dragging horizontal one * Fix clicking on horizontal scrollbar track * Implement `start` scrollbar alignment * Add documentation to `Scrollbar` * Make `DocView` infinitely scrollable horizontally * Handle horizontal scroll SDL event
