Runs lua/repl_prelude.lua at console initialization.
The default prelude contains global assignments for all devilutionx
modules. This should save us on typing.
Scrolling: PageUp/Down and mouse wheel.
History navigation:
* Up/Down navigates the input history.
* Shift+Up/Down navigates the output history (allowing us to copy/paste the
outputs, I imagine this will be very handy).
* Duplicates are skipped.
Enabled only in Debug mode.
Runs Lua similar to the `lua` CLI.
Supports multiline input with Shift+Enter.
Missing features:
1. Scrollback.
2. Input history on up/down.
Open with backtick, close with Esc.
