encoder: See description

Features, Fixes, etc:
- Added encoding 'Mode' selection which allows users to choose between Normal (Single Frame), Temporal (Single + Last Frame) and Sequential (VFW Default).
- Fixed several compiler warnings with mismatched types and unused variables.
- 'Keyframe Interval' and 'Bitrate' now default to 0 (Encoder decides).
- 'Quality' now defaults to 100.0%.
- Added default Quality and Keyframe Interval to log.
- 'Bitrate', 'Quality', 'Configure' and 'About' are hidden when the encoder does not support them.
- Encoder States are stored in-memory during an OBS session.

ToDo:
- Save/Load encoder state from disk.
