Merge #460

460: Different default directories for CLI and ASB r=da-kami a=da-kami

Fixes #437 

Using the same default directory as data-/config-dir has caused unwanted side effects when running both applications on the same machine.
Use these directory names:
- ASB: `xmr-btc-swap-asb`
- CLI: `xmr-btc-swap-cli`

Since the functionality is now application specific the respective functions were moved into the appropriate module of the application.

 ## [Unreleased]
 
+### Fixed
+
+- An issue where both the ASB and the CLI point to the same default directory `xmr-btc-swap` for storing data.
+  The asb now uses `xmr-btc-swap/asb` and the CLI `xmr-btc-swap/cli` as default directory.
+  This is a breaking change.
+  If you want to access data created by a previous version you will have to rename the data folder or one of the following:
+  1. For the CLI you can use `--data-dir` to point to the old directory.
+  2. For the ASB you can change the data-dir in the config file of the ASB.
