* Fixes#398
The new Browser Integration entry settings page has a list view with any additional URL's. These URL's are added to the entry attributes with KP2A_URL_<counter>, which means those are directly compatible with Keepass2Android.
This change adds a GNU Readline-based interactive mode to keepassxc-cli. If GNU Readline is not available, commands are just read from stdin with no editing or auto-complete support.
DatabaseCommand is modified to add the path to the current database to the arguments passed to executeWithDatabase. In this way, instances of DatabaseCommand do not have to prompt to re-open the database after each invocation, and existing command implementations do not have to be changed to support interactive mode.
This change also introduces a new way of handling commands between interactive and batch modes.
* Fixes#3224.
* Ran make format
