Diff -> HTML should respect line numbers from input

I think we need some special tokens for that:

• @encoder.line_number 308 || nil sets a new index, which is automatically increased for each line until another one is set.
• nil turns off line numbers.
• Maybe we need to send a @@encoder.there_will_be_line_numbers@, which would be equivalent to @encoder.line_number = nil.

TBD:

• Do we ignore :line_number_start in such a case?

This is more complicated as we really need two columns (old/new line numbers) for this. Seems more like the Diff scanner will be some special thing in the future anyway.
