Added Delphi XE Project and Group.
It was the only supported version of Delphi that did not have these.

This really was just an Open | Save As of the D2010 version.
Manual edits of the DPROJ to get it open Project Options to open Correctly in XE.
Merge pull request #24 from rlove/DelphiXESupport

Delphi xe support

Changes to DUnitX.Tests.TestFixture to test this behavior,
Note: It does have 2 tests that should fail.   Since this would most likely break CI setups I have wrapped the registration for these test in
 {$IFNDEF CI} {$ENDIF}
