Add new option: --monitor <cmd>
Option lets user specify a command <cmd> that will get
forked by cgminer on startup. cgminer's stderr output
subsequently gets piped directly to this command.
This permits smart batch monitoring of the miner by a
baby-sitter log parser while retaining the full benefit
of the curses interface, e.g. when running cgminer under
screen.
Doing the same thing is possible using advanced bash
redirection paraphernalia, but it is somewhat of a pain,
especially when running screen'd.
This option makes things more straightforward.

Differentiate thread failure from GPU failure by declaring a GPU sick first and trying to restart the thread without re-initialising the card.

Increase efficiency of slow mining threads such as CPU miners dramatically.
Do this by detecting which threads cannot complete searching a work item within the scantime and then divide up a work item into multiple smaller work items.
Detect the age of the work items and if they've been cloned before to prevent doing the same work over.
If the work is too old to be divided, then see if it can be time rolled and do that to generate work.
This dramatically decreases the number of queued work items from a pool leading to higher overall efficiency (but the same hashrate and share submission rate).
