Track the currently typed word

The `CurrentlyTypedWord` class tracks the word that is being typed. It's
implemented on the same model as Autocapitalisation and avoid expensive
IPC calls when possible.

The `Suggestions` class is where the suggestion lookup should go. It
currently just echoes the current word.
