Feature/1.19

[ErisApps]

This PR was intended to be a small one... but ended up being pretty big. Anyways, general list of changes include, but not exhaustive:

• Updating BSMT.T
• Switching from BS-Util configs to BSIPA configs
• Migrating from BS-Utils in general to SiraUtil/Zenject
• Other minor fixes
• Cleanup of obsolete/unused code
