v0.148.1 — History for characters and tokens

• [x] History is now everywhere you look at a character or a token. The Impersonated Token panel, System 8's new character sheet and Mini-Me's … menu had no History button; now they do. On the sheets and the Impersonated Token panel it sits in the panel's top bar, and moves under that bar's … when the panel is too narrow, so the new sheet's History has moved up there too. A token linked to a character opens the character's history. Any other token opens its map's, because a token has no history of its own. Who can see history and who can restore hasn't changed.
