JSON HTTP Handler

Provides hopefully reasonable defaults for JSON HTTP APIs:

• adds Content-Type: application/json to all responses including 404 Not Found
• Recovery from panics with a 500 Internal Server Error and an empty JSON response
• Logging of incoming requests (Log(string) and LogErrorWithTrace(string) methods are required as well as Logger() Logger)
• Passes a struct with pseudo-global variables (db connections, environment variables etc.) to all http handlers (You need to define the Config() Config method, Clients() map[string]interface{} and DB(string) *sql.DB). For more info see the go-pseudoglobals project.

Usage

See tests for a full example

You can use manners instead of http.Server, add signal handling and so on still relying on jsonHttpHandler as the low-level tool.
