Adds methods which allows to get more informations about caches.

Adds the new dependency in the readme, and mention the new Random implementation.

…o Held03-feature

This library now supports Release 2 of the RANDOM.ORG JSON-RPC API.
Updates:
- New methods (generateIntegerSequences, generateSignedIntegerSequences, createIntegerSequenceCache and getResult)
- New optional parameter JsonObject 'userData' can now be used with signed methods returning random values
- Parameter 'base' can now be used on integer and integer sequences methods (Basic and Signed API). NOTE: basic methods 'generateIntegers' and 'generateIntegerSequences' return String values when the 'base' parameter is used, even when it is decimal (base = 10). For int values, simply use the method without 'base' parameter. The same applies to 'createIntegerCache' abd 'createIntegerSequenceCache'. Signed methods 'generateSignedIntegers' and 'generateSignedIntegerSequences' return int values for decimal base, String values otherwise.
- Updated test cases to cover new methods and use JUnit ErrorCollector
- getUsage() is called in the RandomOrgClient constructor to update remaining requests and bits
- Minor bug fix to improve threading for serialized clients
- Added error codes (RandomOrg Errors: 305, 306 and 307)

This library now supports Release 3 of the RANDOM.ORG JSON-RPC API.
Updates:
- New methods (createTickets, listTickets and getTicket)
- Method overloading for all signed value-returning methods to contain the optional 'ticketId' parameter
- Added RandomOrg error codes 420, 421, 422 and 423
- Added tests for all new methods, error codes 420, 421 and 422 and signed methods with 'ticketId' parameter

This library now supports Release 4 of the RANDOM.ORG JSON-RPC API.
Updates:
- Method overloading for all (basic and signed) value-returning methods to contain the optional 'pregeneratedRandomization' parameter
- Method overloading for all signed value-returning methods to contain the optional 'licenseData' parameter
- Added methods to generate the signature verification URL and HTML forms (createURL and createHTML) using the random object and signature returned from any of the signed (value generating) methods; the URL and HTML form link to the same web page that is also shown when a result is verified using the online Signature Verification Form, see: https://api.random.org/signatures/form
- Added tests for methods with the 'pregeneratedRandomization' parameter

Added the new revealTickets method and the accompanying error (426). Also includes tests for the method (revealing a single ticket and multiple tickets) and the error.

Updated the RandomOrgRANDOMORGError class to include the error code as a (private) property, accessible by using the getCode() method.

Also updated the links in the descriptions.
