When host option is specified it will be used instead of the default when creating the URI object

There was a bug where if changing the host to use https://api.pusherapp.com for example the URI object was still created using the pusher default of http://api.pusherapp.com
Updated version to 0.07
Added test for HTTPS option

Added a test case for pushing an event over HTTPS
