closes #896

Hello, I'm trying to use the config module with Tendermint v0.34.x and I found that lots of the options have been changed. I've updated them to be in line with https://github.com/tendermint/tendermint/blob/v0.34.10/config/toml.go.

• Referenced an issue explaining the need for the change
• Updated all relevant documentation in docs
• Updated all code comments where relevant
• Wrote tests
• Added entry in .changelog/

Thank you too,unclog looks very handy for this!

Just a note, the format shown in CONTRIBUTING shows - [pkg] \#xxx Some description about the change, but the other entries in .changelog had a slightly different format, so I followed that for consistency.
