Proposal: Allow user to bind query parameters to structs directly

[QuantumGhost]

Issue Description

Currently echo.DefaultBinder#Bind bind parameters to structs based on request method and content length. More specifically, it only retrieves data from Context#QueryParams when req.ContentLength == 0 and req.Method is GET or DELETE. So it's impossible for user to bind query parameters to structs when request method is neither GET nor DELETE.

I hope that echo.DefaultBinder could add a method BindQuery, which binds query parameters to structs directly.

A even better (but incompatible) change is to add BindQuery method to the echo.Binder inferface, and implement this method in echo.DefaultBinder.

On a side note. This has been resolved, docs are being updated and binding is much more capable now.
