Cristian Dinu ba12f9e81f Implement tabs as spaces

When we load a string in `TextEdit` we keep the tabs as they are.

Now depending on `tab_as_spaces` and `tab_size` properties of the
`TextEdit` we have the following situations:

- When `tab_as_spaces` is false, then when we press `TAB` a `TAB`
  char in added to the string.

- When `tab_as_spaces` is true, then when we press `TAB` a chunck
  of `tab_size` spaces is added to the string.

To config `tab_as_spaces` and `tab_size` to the values we want we
can use the folliwing helper functions:

- `TextEdit::tab_as_spaces()`
- `TextEdit::tab_size()`

Example usage:

```rust
ui.add(egui::TextEdit::multiline(&mut self.multiline_text_input)
    .tab_as_spaces(self.tab_as_spaces)
    .tab_size(self.tab_size));
```

Demo:
A better demo of this new functionality was implemented in the
misc widgets demo

What's left to do:
- Render actual `TAB` as a rect the size of `tab_size` spaces.

- Without default parameters values it seems a pain to implement.

  I need to think if it is possible to avoid API breaking changes
  for the font system. From my checks so far I need to pass at
  least `tab_size` to the fonts system to know how big the glyph
  for `TAB` will be.

egui demo library

this crate contains example code for egui.

it is in a separate crate for two reasons:

to ensure it only uses the public egui api.
to remove the amount of code in egui proper.
