new version which can deploy to railway

[mccoysc]

this is the forked project that has been fixed some bugs.(https://github.com/mccoysc/halbot)

1. the old project would re-init and make telegram bot report:"only one bot can be run at the same time".
2. the old project use "~/.config.json" as config file,but the forked can use process.env.BOT_CONFIG to store config json string.

Rejected.

Actually, adding process.env and railway support is good. I will follow some changes and support env beehive. But I am not going to remove the traditional config file loading.
