- Blood: cleanup and simplification of SEQ code.

Browse source 
* removed all the large instance arrays. None of this is really necessary, all we need is a single dynamic array with only the active sequences that can expand as needed.
* added JSON serialization. With the above change this part now becomes trivial.
* renamed all 'atxx' variables in this code.
