Heroes of Idleville Reborn 0.2.2 (Linux x86_64, test build)

Run:   ./HeroesOfIdlevilleReborn.x86_64
Needs: a 64-bit Linux desktop with OpenGL 3.3. Keyboard, mouse or a gamepad.

Play online: on the title screen pick "Play online" and leave the World field empty.
The game finds the world by itself: reborn-world.heroesofidleville.com. 0.2.1 and older
can no longer join: the servers speak 0.2.2 now. (Testing on the homelab instead? Type
https://reborn-world.home.arpa into the World field.)

New in 0.2.2: hire companions at the Tipsy Turnip and bring them along online, give them
FFVII-style tactics, couch co-op menus per pad, and the party frame.

Offline play works as before and keeps its own heroes.
Rough edges and balance held together with string. The scarecrows have unionised.
