If the dates in `Last-Modified` and `If-Modified-Since` are an exact
match, the server should 304.

13409fd7c6 add support for tiered caches
The -cache flag can be specified multiple times to create a tier of
caches.  Typically this would be used to be put a small in-memory cache
in front of a slower on-disk cache.

0ee5167444 switch to official AWS Go SDK
This uses the official Go SDK from Amazon, which supports the newer v4
authentication method.  Fixes #74.  Doing so also required adding a new
s3cache package which uses the official SDK.

THIS IS A BREAKING CHANGE for anyone that uses s3, since the syntax of
the command line flag is now different.  This is unfortunately necessary
because aws-sdk-go always requires the region to be explicitly declared,
which wasn't always the case with the previous format.  This breaking
change is unfortunate, but given that the other s3 package hasn't seen
updates in years, and so many new S3 regions only support the newer v4
authentication method, it's necessary.

5ee7e282cf return a 200 OK for requests to root /
This has come up a couple of times, such as in #95.  As discussed there,
I'm not completely sure this is actually necessary in many cases, but
it's certainly not harmful and if it makes health checks easier to setup
than why not?

if any transformation is requested, first apply any additional
transformation necessary to correct for the EXIF orientation tag, since
it is stripped from the resulting image.

4533f0c68a allow crop options to be floats and negative
values between 0 and 1 have the same behavior as the size option - it is
treated as a percentage of the original image size.  Negative values for
cx and cy are calculated from the bottom and right edges of the image.
