Fixed Issue #40: Inconsistencies on the return of Cloudlet.isCloudletFinished() and the Cloudlet status.

Fixed Bug #34: Call getVm(vmId, userId) Function had swaped parameters in several parts of the Datacenter class.

Fixed comment on example 2, which said that MIPS requirements were different. Actually, they are the same.

Updated the javadocs, headers, code formatting, and Maven configuration (new versions of the dependencies)

want to disregard amount of MIPS required by VMs and allow oversubscription of hosts.

If more MIPS than available are required in VmSchedulerTimeShared, allocation failed by MIPS.
This does not happen in VmSchedulerTimeSharedOverSubscription.
