Add text field for storytelling

• [x] Text field API
• [x] Events that will put text into the text field
• [x] Combine text messages into a queue
• [ ] Text typing effect

Add a text field where items and characters can write text. It should look like this (doesn't have to be that fancy):

Text could also be written when player passes certain location for the first time.

We can also use zone editor from Tiled to denote zones upon entering which text would appear.

I suggest adding a text typing effect.

Sounds good. We can also add an optional parameter for text zone triggers to invoke special effects.

Done probably.
