Merge pull request #4 from amit-handa/devamit

Devamit
Indentation changes
Moved security stuff to auth manager
Removed response object from request
Moved security stuff to AuthMgr
Removed constant MAC_ALSO_NAME as its moved to AuthMgr
Just formatting
Auth handling enhanced
Invalid sessions hashmap is not required as we are closing channel
Security key should not be hardcoded so moving to config. This should be moved later to ENV variables(security practice)
Renamed AuthMgr->AuthHandler to have name consistency
Removed unused variables
Using MAC for individual channel as its not thread safe and should be independent for each channel
Fixed BUG : static hashset is used by multiple threads.
Instantiating hashset cookies if and when required
Removed IOException from getInstance of Config class as it should be thrown while settingup the config, and once done it will never be thrown as its always readonly. This was getInstance() accessors wont ahve to handle IOException.
Added 'auth-key' key to the config
Changed to ctx.fireChannelRead to deliver the request to next Inbound handler
