This commit changed a few things in the backend and classes code:
* Any <type>_PPS transaction does NOT need to be confirmed
* Queries updated for added <type>_PPS transactions
* Template updated to properly display these transactions
Cronjob
* Added pps_payput cron to run payouts based on worker submitted shares
* **IMPORTANT**: Can NOT be run with proportional_payout!
Addresses #70
* Fetch all blocks unaccounted for in ASC oder (low to high height)
* Use lowest height block to find lowest ID upstream accepted share
* Use this share as the finding share for a block
* Set share as last found upstream share for further blocks
* This only applies if shares are not deleted at all which they should!
