- grunt watch will now abort mid task

- connection's ping method now accepts requestTimeout, path, and method params like
  all the grown-up API calls
- ConnectionPool now managed connection timeouts. When a connection dies a
  timeout object is created to track when the timeout is scheduled and the function
  to call when it does. It also tracks how many times it has run to allow the timeout
  to grow
- Timeouts now grow with use of `config.calcDeadTimeout` which is set to 'exponential'
  by default, but can also be set to flat in order to always use the standard
  deadTimeout. Exponential growth of the deadTimeout is stopped at config.maxDeadTimeout
  which is set to 30 minutes by default.
- Connections no longer have a resuscitate method (too hard to spell). Now the
  method is created dynamically as a part of the timeout object as it just calls
  the connection's ping method and needed to access variables like revive attempts.
- Timeouts were moved to the transport layer, meaning that you need to capture the
  abort method and abort the request yourself if you are handling connections
  directly, ConnectionsAbstract's ping method does this.
