Improvements to `speech.talonvoice.com`

• Keybinding to end recording and go to next sentence
  Would greatly improve the flow when recording many sentences
• Keybinding to end and discard a recording
  Sometimes you just mess up in the middle of the sentence
• Change title to indicate if it's recording
  Would help us do Talon context
• Show recorded time and rms
  Right now I have no idea if my spoken sentence was recorded correctly
• Ability to remove recording
  Unfortunately it's too easy to mess up a recording so would be great if I could remove them
• Don't count empty recordings
  Too short or too faint recordings could be discarded automatically with a warning

Don't worry about removing recordings. Just re-record the same thing again. I'll figure it out in post.

Much of this is out of scope for the current site unfortunately. I have a much more advanced site I want to build but that won't be a priority anytime soon.
