Archidea 0.3.0

• Split view: up to four tabs side by side in one window, one row in the sidebar. Drag a tab from the sidebar
  onto a page: a card shows whether it goes to that page's left or right. Or choose Open in Split View from a tab's
  menu, or press ⌥⌘\ to open a new one beside the page. Each page is a card of its own, and an outline marks the one
  the address bar, back and forward, ⌘W and Find act on: the one you last clicked into. Drag the gap between two pages
  to share the width, double-click it for even shares. In the sidebar every tab of a split has its own close button;
  the last tab left stays as a tab in the split's place. The split's menu separates it, and swaps the sides of two.
  Splits can be pinned and put in folders like tabs.
• The two-finger swipe between spaces keeps up with the fingers and lands in one movement. The sidebar was laid out
  again on every step of the swipe, and the list came back for a moment before the next space slid in.
• Location for sites: the first time you let a site have it, Archidea asks macOS too, and macOS shows its own dialog.
  Before, macOS was never asked and the site waited until it gave up. When macOS has location off for Archidea, a
  card says so and opens the setting.
