Toml comments are not saved with table arrays

[ruckustboom]

One more (less important) bug with comments in TOML

If you add comments to table arrays, only the last one is kept. Here's an example to better explain

[[products]] # Table List 1
name = "Hammer" # Name 1
sku = 738594937

[[products]] # Table List 2
name = "Nail" # Name 2
sku = 284758393
color = "gray"

becomes

# Table List 2
[[products]]
	# Name 1
	name = "Hammer"
	sku = 738594937

[[products]]
	color = "gray"
	# Name 2
	name = "Nail"
	sku = 284758393

Notice the first table in the array is now marked as Table List 2 and the second is not marked.

Tested in 3.0.1

This is related to issue #29 because the table arrays (and their comments) are stored just like normal arrays.
