Increase commons dependency version number

 * Depend on commons:1.0.1 to get ImmutableList support.
Correct timestamp comparisons

Joda DateTime objects equals() compares both the millisecond count since
the start of the epoch, and that chronologies are the the same. This is
means that two objects that represent the same instant can still be
regarded as non-equal, which is not what we want. We just want to
compare the millisecond count since the epoch.
Deal with Amazon filter limits

Amazon imposes a filter value limit at 200 values. Our previous approach
of supplying the instance identifiers as filter values therefore breaks
when the managed set of instances exceeds this value. However, Amazon
provides a method for supplying instance identifiers as something other
than a filter value in the call to describeInstances.
Handle >1000 returned instances

The API specifies that if DescribeInstances needs to return more than
1000 instances, it will do so in chunks of size at most 1000, and one
needs to pass a returned `nextToken` to get the next chunk.
