Add DLL build support and wrapper that allows clients to transparently switch between static and dynamic CEF builds.

- The libcef project now builds libcef_static.lib instead of libcef.lib.
- The libcef_dll project builds libcef.lib and libcef.dll.  This DLL exports the new CEF C API defined in cef_capi.h, cef_nplugin_capi.h, cef_string.h and cef_string_map.h.
- The libcef_dll_wrapper project builds libcef_dll_wrapper.lib.  This static library wraps the new C API calls with an implementation of the CEF C++ interface as defined in cef.h and cef_nplugin.h.
- The cefclient project now uses the DLL instead of the static library.
- Type definitions have been moved from cef.h to cef_types.h so that they can be shared by both cef.h and cef_capi.h.  This change required some enumeration member name modifications throughout the code base.
- Fixed variable naming inconsistencies.
- Added CefVariant::GetArraySize() method and _NPN_ArrayObjectGetVectorSize() function.
- Remove the ProjectSection(WebsiteProperties) sections from cef.sln to improve VS2005 performance.
