Feature/debug menu (#1645)

* Reorganised cells

* Clipping content

* Simplifying Cell and leaving responsibility to modifier and content

* Fixing animations

Also fixing compose copy that wasn't set up properly...

* Debug menu

Added a debug menu
It can be accessed from the settings page or via an app shortcut (from the app icon)

* Finalising the debug menu

We can now switch environments between mainnet and testnet

* Update app/src/main/java/org/thoughtcrime/securesms/debugmenu/DebugMenu.kt
