Fixing encoding of decimals ending in .0 or 0.0

[ahisbrook]

Found an error where storing a BigDecimal ending in .0 or 00.0 would not store/retrieve correctly.
Traced this to the append_decimal method of CqlByteBuffer

Example:
Encoding a BigDecimal of 1042342234234.0 would result in a decoded decimal of -57169393542.0
Encoding a BigDecimal of 12000.0 was unable to be decoded

Sorry, because you closed the first PR I assumed this was the same as #112, but it doesn't look like that.

Please avoid committing unrelated whitespace changes, it makes PRs so much harder to read. This is just a general comment, obviously a single line isn't a big deal.

Thanks again for the PR and for finding this bug. Good catch. If you fix the small comments I added to the diff I'll merge this as soon as I get the time.

Do you need a new gem release soon?

[ahisbrook]

Yes, I'll fix those. Thanks for the quick reply!

A new gem release would be great when you get a chance.

Looking at this code now I realize how much of a hack it is. Can you help me come up with a better way of doing this without going through #to_s -> #gsub -> #to_i? I've been looking at the BigDecimal docs for a while now and can't see anything obvious, but it feels like there's a way to use BigDecial#to_r.

I'll merge this when I can, regardless, but it would be great to have something better for the future.

It is pretty hacky. I'll look at the docs and try to come up with some alternate solutions.
