Release notes for v0.1.0

First release.

• Tap a modifier on its own and it sends a key of your choosing; hold it, or press it with anything
  else, and it is the modifier it always was
• Works before you open it: both Command keys send Escape out of the box
• A rule for each of ⌃ ⌥ ⇧ ⌘, with the left and right side of each treated as a separate key
• Record any key or combination as the output, not just Escape
• The panel shows only the rules you have set. The cog reveals the rest, and holding ⌥ while opening
  it shows everything for that one look
• Hold any modifier and its row lights up — which is how you find a key that System Settings has
  remapped, since a remapped key reports as the right-hand side wherever it physically sits
• Adjustable hold threshold: how long a press may last and still count as a tap
• Per-app exclusions, for terminals, virtual machines and remote desktops
• No Dock icon and one menu bar item, which you can turn off too. Launching Momentary while it is
  already running opens its settings either way
• The menu bar mark dims while Momentary is off, or while another app holds secure input and no key
  press can reach it
• Needs Accessibility permission, and asks for nothing else
