* Refactored Cloudinary Java into multiple modules without breaking the module naming convention already established.
* Created a -taglib module to support constructing file input tags on the server side, since it requires some server side API signing.
* Separate modules allow users who are writing stand-alone applications (not depending on the Servlet API) not to have a dependency on it.
First pass at an upload tag and support code
renamed tag to make more sense
correctly located the cloudinary tld and updated to use the new classname of the tag
Added a singleton manager to ease spring support.
cleaned up the tag rendering. There is some more flexibility that needs to be added to the tag, but it looks like the core of it is working ok.
