0.3.0: Add support for secondary indexes

Last release with the deprecated methods:
* appendToListOnKey
* removeFromListOnKey
* isInListOnKey
Receive table names as parameter

Now instead of the prefix to build our own table names,
DynamoKV receives an object like:
{ "TABLE-A": "prefix-and-whatever-TABLE-A-whatever-else" }

To know the mapping between the short names and the dynamo
tables.

This is Beanstalk friendly.
0.4.0: Receive table names as parameters

Instead of receiving a prefix a figuring out the
real table name in dynamo, we receive an object
with the short->dynamo table name translation.

This object (in a file) can be generated with BeansTalk.
0.4.1: Previous version wasnt uploaded correctly

Mock patch release with no real changes.
