Change Windows CRLF line endings to Unix LF endings.
crt-royale:
Added an INTEGRATED_GRAPHICS_COMPATIBILITY_MODE option for Intel HD 4000
Graphics (and Intel-specific settings files in crt-royale-settings-files).
This lets crt-royale run on Intel HD chips at reduced quality when enabled.
It's disabled by default to avoid silent quality regression on ATI/nVidia.
Updated README.TXT with corresponding information and forgotten details.
Renamed levels_underestimate to bloom_underestimate_levels for clarity,
and increased its max value.
