Shared Host Upgrades by Schleimi

Host-only shared upgrades for R.E.P.O.

Install it on the host only. Use an upgrade and the whole team gets it.

The host keeps the shared upgrade values and synchronizes them to the team after the map starts. After an upgrade, synchronization waits briefly and sends corrections one at a time to avoid overlapping REPO's own upgrade processing.

All upgrade effects use normal R.E.P.O. vanilla values.

The mod waits until player avatars are fully loaded before synchronizing. Tumble Launch is intentionally not shared because its current Vanilla RPC is unstable.
