bugfix: panic when type unmatch between toml and struct

[jayi]

When type unmatch between toml and struct, will panic.

Example:

type Postgres struct {
	Id int64
}
type Config struct {
	Postgres Postgres
}

doc := []byte(`
[Postgres]
Id = 1e3
`)

config := Config{}
toml.Unmarshal(doc, &config)
fmt.Println("id=", config.Postgres.Id)

Panic:

panic: reflect: call of reflect.Value.Int on float64 Value [recovered]
	panic: reflect: call of reflect.Value.Int on float64 Value

Thanks for your PR! Looks like it's also gonna help with #219! I pulled your changes and tried with the example you gave, but I'm getting config.Postgres.Id equal to 0. That doesn't seem like the expected output?

[jayi]

id= 1000

This is the output I got, it seems ok?

[pelletier]

Interesting. With

type Postgres struct {
	Id int64
}
type Config struct {
	Postgres Postgres
}

doc := []byte(`
[Postgres]
Id = 1e3
`)

config := Config{}
toml.Unmarshal(doc, &config)

fmt.Println("id=", config.Postgres.Id)

I get id= 0. Which version of go are you using?

[jayi]

1.9.2

Thanks! Sorry took so long to merge that. I was actually doing something silly, the patch works well.

Thank you!
