Updated feature: Some modifications & refactor

+ Renamed Gleez::$_ginit to Gleez::$_init
+ New codename
+ New version
Fixed issue: Fixed CURL config
Fixed issue: Fixed version & codename for user agent
Fixed issue: Removed not needed checks

If Kohana::init has been called, we don't allow execution
Kohana::init twice. In this case Log and Config objects are
created once.
