Added support for dragging target on WPF windows and building simple
xpath statements. Fixed some null results in native library and
increased performance of enumerating wpf windows. Still need to tweak
filters for picking up Silverlight handles too.
The WpfBridge native library can now enumerate all WPF and Silverlight
Windows and list them in Synthuse. Still need to add a method to
connect the Drag Target to locate the WPF window.
Commands are categorized in to sections, Keyboard, Mouse, Windows, File,
and Main.
The open command will open an application.
The displayText command displays a status text for a period of time.
Added unit test for CommandProcessor.
Sendkeys didn't like certain built-in VK constants, instead have to
combine shift + 1,2,3,4...
Also removed external jna dependencies, since ivy/ant can download them
with the command: ant resolve
