Chalice: Introduced '[[ S ]]' as a shorthand syntax for 'lock (this) { S }'. Think of the new brackets as atomicity brackets (see PetersonsAlgorithm.chalice)
Chalice: Added Peterson's algorithm to test suite (safety properties only)
VS 2010 integration: Updated Chalice and Dafny modes, added keyword highlighting for a new Boogie mode
