Sort stories, show status & date in selection UI, and add some more keybindings to selection UI

Bugfixes:

• fixed an issue (sometimes) getting the Pivotal API key from git-config by trimming space from the resulting string

New features:

• stories are now sorted most-recently-updated first (refresh your stories to see the effect)
• in the selection UI:
  • story status is now displayed
  • story last-updated timestamp is now displayed
  • added keybindings:
    • G for jump to end
    • g for jump to top
    • n for next
    • p for previous

Upgrade Notes:

There might be a problem when it tries to load your cached stories file made by the previous version. Either delete the cached file (~/.gg-git-hooks-cache.json) or preemptively run:

goodguide-git-hooks update-pivotal-stories

Allow setting pivotal token via environment variable

Allow getting pivotal token via ENV

Fix some bugs

Fixed:

• bug when updating list of stories -- cursor didn't reset so would appear lost in some circumstances.
• stories are now excluding those marked delivered

Selecta replacement

I had removed Selecta support for attaching a story tag after the message editing step in the commit process during the first iteration of the rewrite, as I found the UX to be kludgy anyway. With this release, I've added a nice termbox-based UI for interactively selecting a story.
