* Remove stuff which isn't being used
Some fields, functions and structs aren't in use by the project. Remove
them for janitorial reasons.
* Remove more unused code
All of these functions are currently not in use. Clean up the code by
removal, since the version control has the code if need be.
* Remove unused functions
There's a large set of unused functions and variables in the code base.
Remove these, so it clearer what code to support going forward.
Dead code has been eliminated.
Where applicable, comment const-sections in tests, so reserved
identifiers are still known.
* Fix use-def of tsURL
The first def of tsURL doesn't matter because there's no use before
we hit the 2nd def.
* Remove dead code assignment
Setting logFile = "" is effectively dead code, because there's no use
of it later.
* Comment out found
The variable 'found' is dead in the function (because no post-process
action is following it). Comment it for now.
* Comment dead code in tests
These might provide hints as to what isn't covered at the moment.
* Dead code removal
In the case of constants where iota is involved, move the iota so it
matches the current key values.
This avoids problems with persistently stored key IDs.
* Make config instance-based
* Remove config dependency in paths
* Refactor config init
* Allow startup without database

* Stash not mandatory
* Panic on missing mandatory config fields
* Redirect setup to main page if setup not required
* Add migration UI
* Remove unused stuff
* Move UI initialisation into App
* Don't create metadata paths on RefreshConfig
