Use std::unique_ptr<> to pass frame ownership in DesktopCapturer impls.

Previously raw pointers were used for owned DesktopFrame instances.
Updated all screen and window capturer implementations to use
std::unique_ptr<>.

Also includes some other cleanups in the capturers:
 - s/NULL/nullptr
 - moved default initializers to class definition.
