FIX: Fix Pyglet text rendering

@Eric89GXL Add option for line wrap to `screen_text` and `screen_prompt` and changed 'visual.Text' so that 'multiline=true' is not default
Please use as little vertical space as possible, like:
```
scr_txt = Text(self, text, pos, color, font_name, font_size,
               wrap=wrap)
```
Or whatever is required to stay within PEP8 / 79 char.
