Turned off Doomfist by default - Doomfist was causing crashes and needs re-working

Added Ultimate options for zombies:

Off
Self nanoboost (nanoboosts the zombie when they hit full ult charge)
Standard (uses ult when they hit full charge if they have a target; Echo ult is permenent)

Ran the code through zezombye's overpy optimizer

Added server load dev option

Updated code to avoid over-spawning of unique heros

Disabled Spectators due to known workshop bug

Better AI Hanzo

Optimised the code a whole bunch

Fixed bug that was causing some echos to respawn at incorrect times

Fixed bug that allowed late-joining players to pick outside of hero limits (sometimes wipeing enemies)

Changed Doomfist to be default choice for miniboss

Reordered the new enemy types for a better flow

Refined Doomfist a bit, added dev options

Brought code over to Live with some bugfixes

Updated 'search' pathing (more robust but slower)

Replaced Torbjorn mini-bosses with Doomfist (starts with full shield, is fully programmed to fight)

Changed next-round countdown 'pause' to 'reduced speed' when players are selecting hero

Added ult Store when swapping to the same hero

Changed default options

Added option to start on later waves

Added 'dead or echo' as duplication target

Added additional AI support for Zen, Mei, Ashe, and Junkrat

Fixed copy-paste issue (was using disabled effects)

Fixed a bug where ai would avoid inclines

Added 'duplication target' options so hosts can have them happen more often or remove the zombie's respawn

Added first wave number mod so bigger teams can get into the action faster

Improved wall detection and UX, fixed survival bug

re-worked pathing to hopefully be more concise

limited max zombies alive to 12 for performance reasons
