Server Code Cleanup

[m1k1o]

Moving things around to where they belong to get better abstraction and separation.

Remote joined Xorg and Gst but they are completly independent tools doing own work:

• Desktop - interaction, control, settings, state of X server (or other protocols in the future).
• Capture - handles video and audio capture.

No API, Config or behavior changes will be made. This is only reducing technical debt.
