Adding a "font-family" property for text objects. (#1311)

- Tiled displays your system fonts.
- Computers have different sets of fonts. Therefore, browsers never rely on system fonts
- Which means if you select a font in Tiled, it is quite unlikely it will render properly in WorkAdventure

To circumvent this problem, in your text object in Tiled, you can now add an additional property: `font-family`.

The `font-family` property can contain any "web-font" that can be loaded by your browser.

This allows us to use the "Press Start 2P" 8px font in text objects, which renders way better than the default "Sans serif" font of your browser.

+
+## Solution 1: design a specific tileset (recommended)
+
+If you want to write some text on a map, our recommendation is to create a tileset that contains
+your text. You will obtain the most pleasant graphical result with this result, since you will be able
+to control the fonts you use, and you will be able to disable the antialiasing of the font to get a 
+"crispy" result easily.
+
+## Solution 2: using a "text" object in Tiled
+
+On "object" layers, Tiled has support for "Text" objects. You can use these objects to add some
+text on your map.
+
+WorkAdventure will do its best to display the text properly. However, you need to know that:

+**Pro-tip:** By default, WorkAdventure uses the **'"Press Start 2P"'** font, which is a great pixelated
+font that has support for a variety of accents. It renders great when used at *8px* size.
