Reimplemented `delete` command as more of a `reset` command

Pressing `d` in normal mode causes the current embedded terminal to be destroyed and the containing terminal item to be reset into its initial state.
This allows for much more flexible usage of _MetaTerm_.

To prevent unnecessary terminal item instantiations the `onExecuted` signal was extended to provide a `index` argument containing the sender terminal's index.
