v0.91.1 - update nag fix (patch)

Windows portable build (x64) of OpenRCT2-Access.

How to use: unzip anywhere and run openrct2.exe. You still need your original RollerCoaster Tycoon 2 game files. nvdaControllerClient64.dll is bundled so NVDA speaks out of the box.

Patch over v0.91. Same features as v0.91 — this only fixes the accessibility updater, which had a hardcoded version that never matched the release, so it falsely announced an update on every launch. The version now comes from a single source that moves with each release, so v0.91.1 stays quiet when you're up to date.

If you're on an earlier build you'll still hear the false prompt until you install this one.
