Subkeys are not dumped together

[xNinjaKittyx]

This may not actually be a bug, but it would be convenient if the parent keys were grouped together.

Instead of

[vwefoin.sfxsfx]
ip = "8.8.8.8"

[mxvin.mxvin_1]
key = "value"

[mxvin.mxvin_2]
key = "value"

[mxvin.mxvin_3]
key = "value"

[mxvin.mxvin_4]
key = "value"

[vwefoin.sfxsfx.memes]
obiwan = "hello there"

It should dump like this:

[vwefoin.sfxsfx]
ip = "8.8.8.8"

[vwefoin.sfxsfx.memes]
obiwan = "hello there"

[mxvin.mxvin_1]
key = "value"

[mxvin.mxvin_2]
key = "value"

[mxvin.mxvin_3]
key = "value"

[mxvin.mxvin_4]
key = "value"

If previous behavior is also desirable, perhaps support different sorting policies?

From your explanation, this looks like a duplicate of #88
