5b79bc6fb7 Set default encoding to R8G8B8 RAW 
This the most trivial RGB encoding the encoder supports. Setting
it prevents a crash related to BW8 only supporting RAW encoding.

adb8e45d67 Fix TGA file writing on Windows 
Before this patch, the tga_encoder mod would write corrupted TGA files
on Windows: Bytes that looked like newlines were replaced by a carriage
return and a newline.
