* jam: update max absolute fee to suggested amount
see suggestion by openoms: https://github.com/joinmarket-webui/joinmarket-webui-docker/pull/25#pullrequestreview-899878865
* jam: restore default config on application start
The image contains a slightly adapted config:
- Enable onion irc servers by default
- Set max/min fee settings (otherwise unset)
Opting out of this behaviour can be done by removing
the environment variable RESTORE_DEFAULT_CONFIG.
* jam: fix typo in description
* jam: update from v0.0.3 to v0.0.4
