Small changes to visuals.
Using another method to get all user collections.

This might still not be the right one.
Reworked the code a bit.

Moved service call functions into a standalone file. Added a functionality to replace links to uploaded resources with code that would download the resource (reusing the logic from KnowBrain; has the same limitations of working only with latest versions of Chrome and Opera). It might be a good idea to get it running using WP PHP side. Just create a page that would be passed some parameters and will just trigger the file download. This would require implementation of direct SSSREST calls from the server-side. This way we would not be exposing the credentials.
Added tagcloud font size calculation logic.
Additions to README file.
Services on PHP-side.

First steps to create connection to to SocialSemanticServerREST on the server side. Only the authCheckCred and userLogin methods are implemented. Implementation is unable to handle errors as of the moment.
