Crate mobugsnag

This is my beginning of a crate for Bugsnag alerting right now it is very minimal and just for my testing use.

See Client for examples

Structs

BugsnagError	The Bugsnag api specifies that requests are processed asynchornously. Therefore, a ‘bad’ request does not necessarily return an error status Errors returned from the api are likely formatting, structure or low-level network issues
Client	The Client is our connection to the bugsnag api. This uses the builder pattern for configuration. See examples below.
