Untrack binary driver/installer payloads

Adds .cab, .sys, .dll, .inf, .cat, .dl_, .da_, .ch_, .in_, .ex_, .ds_,
.msp, .mst, and Thumbs.db to .gitignore. Removes 575 previously-tracked
binary files from the index (files remain on disk, just no longer version
controlled). Keeps .iss/.ps1/.md/.config source tracked.
