When I tried to start the server using the command `./gotosocial server start --config-file ./config.yaml`, I got the following error:
```
root@gotosocial-experiment:/gotosocial# ./gotosocial server start --config-file ./config.yaml
Incorrect Usage: flag provided but not defined: -config-file
NAME:
gotosocial server start - start the gotosocial server
USAGE:
gotosocial server start [command options] [arguments...]
OPTIONS:
--help, -h show help (default: false)
FATA[0000] flag provided but not defined: -config-file
```
Putting the flag after the `./gotosocial` but before the `server start` seems to work properly
* start pulling out + replacing urfave and config
* replace many many instances of config
* move more stuff => viper
* properly remove urfave
* move some flags to root command
* add testrig commands to root
* alias config file keys
* start adding cli parsing tests
* reorder viper init
* remove config path alias
* fmt
* change config file keys to non-nested
* we're more or less in business now
* tidy up the common func
* go fmt
* get tests passing again
* add note about the cliparsing tests
* reorganize
* update docs with changes
* structure cmd dir better
* rename + move some files around
* fix dangling comma
* move scripts, allow testing both dbs with one cmd
* tidy + vendor
* update test.sh to ignore cache
* put test commands directly in drone.yml
* change CONTRIBUTING slightly
