Source/JavaScriptCore:

* JavaScriptCore.xcodeproj/project.pbxproj: Copy InspectorJSBackendCommands.js to the
private headers directory.

Source/WebCore:

* WebCore.xcodeproj/project.pbxproj: Copy InspectorWebBackendCommands.js to the
private headers directory.

Source/WebInspectorUI:

Copy the backend commands generated in other frameworks into our built products directory.

* Configurations/WebInspectorUIFramework.xcconfig: Set up variables so we can pull backend
commands files from the private headers directory of other frameworks.
* Scripts/copy-user-interface-resources.sh: Always ditto inspector backend commands.
* UserInterface/Protocol/InspectorJSBackendCommands.js: Removed.
* UserInterface/Protocol/InspectorWebBackendCommands.js: Removed.
* WebInspectorUI.vcxproj/WebInspectorUIPostBuild.cmd: Copy over the generated
backend commands files from the other frameworks.
* WebInspectorUI.xcodeproj/project.pbxproj: Add JavaScriptCore and WebCore as
framework dependencies so Xcode builds them first.

Source/WebKit2:

* PlatformGTK.cmake: Copy over generated inspector backend commands files.

Tools:

* Scripts/build-webkit: build WebInspectorUI after WebCore but before WebKit.
