Volfram

This is a fork of Element Android, with slight modifications mainly to the UI.

Based on the 1.6.5 release of Element
Show grey shield instead of red for messages that were encrypted by a logged out device
- Mautrix-whatsapp bridge's all messages have this, at least in some conditions
Use black theme instead of dark when set to follow system theme
New icon, name and logo to differentiate from upstream and allow simultaneous install

All credits belong to devs of https://github.com/vector-im/element-android, I barely know what I'm doing with Kotlin.
