Add QueryParamForm

[isairz]

CaptureAll is exist, but QueryParamAll is not.

I suggest QueryParamAll to get all list of query params.

-- /books?title=eq.servant&category=eq.haskell
data QueryParamAll a b
type MyApi = "books" :> QueryParamAll ByteString ByteString :> Get '[JSON] [Book]
books :: [(ByteString, Maybe ByteString)] -> AppHandler ByteString
books filter = ...

I think it is not hard to implement this because QueryParam alreay do parseQueryText

I think it would be nice if we instead use ToForm/FromForm from http-api-data and parse have a combinator to parse all query parameters using those:

type MyApi = "book" :> QueryParamForm BookSearchParams :> Get '[JSON] [Book]

Your version of QueryParamAll would then just be a special case with

type BookSearchParams = HashMap Text Text

It looks cool!

I think I can create a pull request tomorrow.
