request.GET ignores blank values

[fangpenlin]

When you pass blank query value like

foo=

then request.GET will be empty instead of having {'foo': ''}

[fangpenlin]

should pass keep_blank_values=True for parse_qsl

1. There is impossible to pass parameter to .GET property.
2. keep_blank_values=False is reasonable default.
3. There is request.query_string request's property which allow to manually parse query string preserving blank values.

As result I suggest to close the issue as wontfix.

@asvetlov I am okay with this, but is it possible to assign a custom request class while creating application? so that I can inherit the request class, define my own stuff, including a override GET with blank values.

[asvetlov]

@victorlin I don't want to allow web.Request customization. At least for now.

1. I don't see strong reasons for that.
2. The constructor parameters are not part of public API now, and they are changed very quickly between releases. I don't want to publish those unstable API parts.
