Implement Cutscene Prototype

[lorecrafting]

MVP:

1. Play a cutscene upon new character login.
2. Play a cutscene when picking up a certain object.

A cutscene consists of clearing out the Main Display and only displaying paragraphs, with optional images. Click or touch to move to next section. In future versions, words will slowly spell itself out with narration, with branching decisions also. For prototype just make a paragraph centered in the screen and click to advance.

Notes:
Will use EvMenu to implement this

Upon triggering a cutscene, the server will probably send a custom OOB data object to the client, then the client can handle it.

Just need to overload the at_get hook in a DefaultObject to trigger a call to evMenu to play a cutscene when picking up a certain object.

[lorecrafting]

Able to implement triggering a custcene when picking up an object by activating EvMenu in the at_get hook of an object. Cutscene's are simulated by using EvMenu and just giving one option, per node so that the menu flow goes in sequence.

Next up, need to prototype a way for the UI to go into "cutscene" mode when it detects a cutscene being played. This may include modification of the backend to send a signal to the frontend upon cutscene activation. still don't know where to trigger that message.
