Merge pull request #63 from zathras-crypto/michael-0921_z

Renamed total_tokens to num_tokens to make it more appropriate for TX51
send to owners distribution raw code, for unit testing
Merge branch 'michael-0921' of https://github.com/mastercoin-msc/mastercore into michael-0921
Send To Owners tweaks: rounding, better display of sent_so_far
out-of-range check on 8byte integer: #define MAX_INT_8_BYTES (9223372036854775807)
cosmetic: out of range comment
rounding up on Send To Owners per spec, instead of rounding: ceil()
commented out my HACK
