Enhancement: better serialization; Bug Fix: urllib3 warnings

- Bug Fix: Disable urllib3 warnings from requests because one is activate that is verbose, useless, and just plainly a bug
- Enhancement: Updated serialization/deserialization to work in two manners:
	- if you want json serialization then use to_json()/from_json()
	- if you want to just serialize then use serialize()/deserialize()
	- all json conversion is done only at the level that json serialization is used, anything below is normal serialization in order to limit the escaping of the json data
Enhancement: Version Update

- previous alpha releases have generally been good enough that it's time to move to beta releases
