Subject: Implement `cd` command to enable changing _MetaTerm_'s working
 directory

Exposing access to the working directory to QML is the first step towards enabling usage analogously to a normal terminal emulator alongside the management of multiple running appications.
i.e. executing `cd` should change the global working directory so that consecutive commands work as expected.
