* Difficulty indicator improvements
1. Clean up positioning code.
2. Do not show for non-save portraits.
3. Remove `vecDifficultyIndicators` - render the items on the fly instead
The format is almost identical to CL2, except it uses the frame header
to store frame width and height instead of 5 32-line offsets.
This means we always have access to frame dimensions, so we can use it
as an on-disk format for our graphics as well.
Additionally, we may be able to optimize the rendering even more
in the future now that we have guaranteed knowledge of frame dimensions.
- Use UiOkDialog() to display all error messages
- Add SDL simple message, and console fallbacks to UiOkDialog()
- Boot graphics early on to facilitate most error messages with build in
gui
- Some more miniwin clean ups
