Implement the Show Message Event Command

[AerunDev]

As a game developer
I would like to display text messages to players
So that they can enjoy the game main plot & NPC dialogs

References

• Node's design
• Editor's design

Acceptance Criteria:

• User can write messages
• Events messages are placed in one CSV per event with the first event being 500000.csv
  • Make sure events are always referring to the right CSV and row, and do reuse CSV rows if there are not anymore (like Pokémon forms)
• Messages can be quickly translated from the text input itself (like Pokémon names)
• Messages can be read & displayed by PSDK
• Messages can be skipped or not (Boolean isSkippable)
• Display if there is a speaker or not on the Node, and the speaker itself
• Create the related documentation (unscoped but will be mandatory if someone need it on the following commands to implement)

Things to know

• We won't implement the window settings management in this story too, but in Customize message window settings #592.
• Rich Text Editor is not in the MVP of Pokémon Studio version 3.
