The default attribute on a tuple like variant now causes the to_string
and display format to use the value of the tuple rather than the name
of the variant.
E.g. Color::Green("lime").to_string() will equal "lime" not "Green"
Fixes: how to round trip Display and EnumString with default="true" #86
BREAKING CHANGE
This changes how Display and ToString cause the following to renders:
```rust
#[strum(default)]
Green(String)
```
To maintain the previous behavior (use the variant name):
```rust
#[strum(default, to_string("Green"))]
Green(String)
```
