Equals overrides cleanup and execution of XUnit tests on build

drub0y commented 12 years ago

cleaned up implementations of Object::Equals, IEquatable::Equals, ==, != on GitObject, CommitVertex and CommitEdge so that there is one core implementation and all others defer to that internally
added support for running XUnit as part of the build by importing the XUnit MSBuild task from the \packages dir and executing it when the RunXUnitTests property exists (right now only in the Debug configuration)
also merged these changes with changes were made simultaneously to GitObject in upstream/master

Looking pretty good, but some changes left me concerned with a potential null ref. Thanks for your help!!! :metal:

Small updates needed for LHS null ref checks in operator overloads.
