Reword warning about undefined bsonWoCompare

Reword warning about the number of orphaned documents counted in mongo
shells that lack the bsonWoCompare function, i.e. before 2.5.3.
First commit of balancer.js script

The balancer.js script is used to split and move chunks. Rather than explain
everything in this comment, I'll create a README.
Fixed several issues causing code to not load or run as intended.
//TODO Remove logging of replSet checks when in verbose false mode.
Updated README.md to show new options.
Updated code to simplify  and use  Orphanse.setOutputNS(XXX).
Add Orphans.preFlight() to  so connection setup seperately , for output parsing.
Removed  debug printing of options.
Specify chunk range and multi destination shards

There is a new method called Balancer.setChunkRange(first, last). This
restricts the chunks considered to those whose min falls within this inclusive
range.

There is a new method called Balancer.setDestShards([string]), that allows
you to specify an array of destination shard names. Chunks will then move
alternately between the specified destination shards.
Support _secondaryThrottle and _waitForDelete

There are new methods: Balancer.setSecondaryThrottle(b) and
Balancer.setWaitForDelete(b) that set these respective. These methods set these
values for chunk moves.
