490: Mainnet switch r=da-kami a=da-kami

Fixes  #446
Fixes #360 
Fixes #506 
Fixes #478 

To be precise: It is actually a testnet switch, because I think mainnet should be default.

I took several assumptions on the way (e.g. network support, ...).

At this stage any feedback welcome :)

TODO:

- [ ] successful mainnet swap with this code base before merging :)

1. Balance of ASB too low
2. Buy amount sent by CLI exceeds maximum buy amount accepted by ASB
3. ASB is running in resume-only mode and does not accept incoming swap requests
- An issue where the monero daemon port used by the `monero-wallet-rpc` could not be specified.
The CLI parameter `--monero-daemon-host` was changed to `--monero-daemon-address` where host and port have to be specified.
### Changed
- The ASB's `--max-buy` and `ask-spread` parameter were removed in favour of entries in the config file.
The initial setup includes setting these two values now.
- From this version on the CLI and ASB run on **mainnet** by default!
When running either application with `--testnet` Monero network defaults to `stagenet` and Bitcoin network to `testnet3`.
This is a breaking change.
It is recommended to run the applications with `--testnet` first and not just run the application on `mainnet` without experience.
