v.0.5.0

This is a major update, which now makes it possible to exchange objects of any complexity through URL parameters automatically, plus use merging logic for parameters.

When setting defaults (method setDefaults):

• Empty segments are now skipped
• Parameters that do not exist are now merged with the ones that exist

When building a string (method build):

• Parameter values (params) that are not strings, are first converted into a JSON string, and then URL-encoded.
