Updated to BTA 7.3-pre1!
Note: As BTA has gone through various internal changes for 7.3, those changed are reflected in halplibe as well, this release is strictly incompatible with any BTA version before 7.3-pre1, and mods that have halplibe as a dependency will need to undergo non-trivial updates!
Full Changelog: 4.1.3...5.0.0
