Fix all upscaled lockscreen drawables and add a few

Several of the original CM9 drawables were upscaled
from a lower quality source. I rescaled some from the
originals and recreated the missing ones in vector
format plus added some new ones.

Lockscreen : Update camera availability check
Make the default availability of the target dependant on the
availability of a camera rather than the presense of a predefined resource.

Also update .Camera to .CameraLauncher since that is what we default too.
