v2.1.35-fork.7

• Deleting Ama's chats: History in Ama's window has Delete Chat, to
  delete one past chat, and Delete All Chats…, to delete all but the one
  running, each after a confirmation. A deleted chat leaves Ama's
  History; its agent keeps its own record of it
• Ama's window no longer has Clear, which cleared the screen of a
  full-screen agent and so did nothing
• Ama's header has room between the frog, Ama's name and its status
• The frog's dot for an answer you haven't read is the theme's green, not
  grey on the grey frog
• A confirmation in a small window, as Ama's can be, keeps a margin
  around it
