Build 26386350

BALANCE
- Classic: fewer Spitters before wave 30 (max 2 per wave); wave 30 onward stays at max 3
- Spitters now fire from closer and less often
- Barricade Kit repairs 35, up from 20
- Reinforced Frame raises the wall's maximum by 30, up from 10

NEW
- New workbench item: Field Engineer, repairs 8 barricade after every wave

FIXES
- Shielded heavy could bestunned just outside the field, wasting player's time
- Workbench: long item names are no longer cut off, and translated text that still doesn't fit shows in tooltip
