Add RouterPattern to context.Input

Right now beego adds this param only in dev mode, but I noticed that it's very useful to have in prod environment to.
My current use case - filter that sends logs in newrelic. Pattern there will help a lot to generate correct transaction name.

fix a spelling mistake

Support load app config before test Beego

improve Swagger

1. Add yaml
2. Fix typo scurity => security
3. Make license optional

Add support "SELECT FOR UPDATE" to orm. Resolve issue #2157

Fix the typo

RequestURI captures the signature field as well.

This in turn results is failure of signature based validation. So what is need is only "/api/resource/action". which is given by ctx.Input.URL()

beego.ParseForm() improvement
