Voxel Phone

This is a massive leap of several mod iterations while bug hunting some problems with icons, group messages, and contact photos. 

• Fixed a KubeJS lifecycle bug wherein app registered after startup were not revalidated for local icons, meaning you only ever got one try to get link a custom icon to a custom app and couldn't update it afterwards.
• Contact Photo Picker no explicity requests gallery metadata, fixing an intermittent empty gallery bug.
• Custom Apps can now use local server icons without a web server by placing the icon into <world>/voxelphone/custom-app-icons/ and ensuring that the icon is perfectly 24x24 (if you want higher than that, you'll need to deploy a theme).
• Fixed an issue with custom app icons not being captured on the screen texture that gets applied to your VoxelPhone's item form.
• Group text messages no longer work like distribution lists; meaning messages are now persisted a single time and not copied per recipient.
  • Each message records the exact recipients at the same time.
  • Members added later cannot see prior messages.
  • Members who have been removed retain messages already delivered to their devices.
  • Per-recepient read state and finite mailbox retention are reserved.
  • Attachements work from the shared message record.
  • Direct-message threads no longer include group texts.
  • Adding a new contact now opens a selectable, scrollable contact picker (it was just force-adding contacts chronologically before)
  • Group, Member, and Picker lists all scroll.
  • Group membership limits are enforced for both the owner and added phones.

This is the version of the app I'll be carrying into the NerdiCorgi's Laboratory modpack update 1.2.5 once it's approved and publicly visible on CurseForge. That means that updates for this will slow down to a rate of approximately once per week unless something catastrophic is discovered or I have an idea that I'm too excited to delay implementing.
