bbhost v0.2.13

The first release from the new repository. bbhost is now licensed under the GNU GPL, version 3 or later, and comes with new documentation in docs/.

• The live server, thehuntersdream.com, now takes only encrypted (https) connections and plays only with signed-in players, as the playtest server did. New installs are set up for it, and a configuration from an older release that still connects to it over plain http is updated at the first start. Sign in with F10 > Account, or in the setup window's Account section.
• Graphics cards with 8 GB of video memory no longer draw the world black. Copies of the game's mesh data now only use the video memory that textures and render targets leave free, and anything that finds video memory full moves to system memory instead of failing.
• On AMD graphics cards, OBS's Vulkan game-capture layer is kept out by default; with it, the GPU of an RX 580 hung on every start. The new [video] obs_capture setting changes that, and OBS's Window Capture works without the layer.
• Graphics cards without Vulkan's maintenance8 feature (older AMD cards, for example) now get valid shaders for the game's offset texture samples.
• bbhost.exe has an icon, and Properties > Details shows its version.
• A setting that bbhost had added to an older configuration file with a note after it ("# added by bbhost ...") was read with the note as part of its value.

The packages no longer include the debug menu's font. docs/running.md ("The debug menu") says where to put it.
