tweaked zombie and leshrac wave spell damage down, reduced lich spawn rates slightly

changed HP scaling of bosses to be less lategame
upped spell damage of bosses to be more earlygame (same-ish lategame)
fixed error that causes the game to stop if a unit was cleared too early

forgot to make shop global in new map

changed event map layout, i didn't like it

returned to previous version of spell scaling, should be less laggy, fingers crossed

changed how spells are amped, no longer visual on tooltip and uses spell amp instead; hopefully actually fixes the lategame lag while i figure something out

tried optimizing the spell scaling on enemies to improve frames
fixed crash when someone DCs
fixed certain boss items dealing 600 million damage
activated multiple hero selection on event, allowing you to have 10 shadow fiends if you roll em

fixed roshan wave causing the game to break

## General
- Treasure round removed, players now start with 3500-5000 (based on map) gold and start at level 1.
- changed how bosses scale
- MMR gain and loss is disabled during this experimental period
## Event - Roguelite
- Added Roguelite map. Heroes don't receive any gold (including starting gold), instead heroes receive 2 items of an appropriate tier every round.
- Neutrals don't have a bounty.
- Bottle removed, instead each hero starts with an Aegis of the Immortal.
- Round 1-5 drop Tier 1 items (Base).
- Round 6-11 drop Tier 2 items (Blue).
- Round 12-18 drop Tier 3 items (Red).
- Round 19-24 drop Tier 4 items (Gold).
- You can sell these items for half their shop value and buy items from the shop still.
- Heroes are randomized for every player, like Single Draft. The same hero can be available multiple times.
- There are only 25 rounds available. Bosses are split into pools. This means the order of bosses is random every game. The next 5 rounds are displayed on the UI.
