Add some validate functions

/object/login/2009/07/11
parse to ObjectController  Login function
params:map[0:2009 1:07 2:11]

Fix utils test fail

Add ParseForm Function & utils test

I guess write would be better

+//Add("/user",&UserController{})
+//Add("/api/list",&RestController{},"*:ListFood")
+//Add("/api/create",&RestController{},"post:CreateFood")
+//Add("/api/update",&RestController{},"put:UpdateFood")
+//Add("/api/delete",&RestController{},"delete:DeleteFood")
+//Add("/api",&RestController{},"get,post:ApiFunc")
+//Add("/simple",&SimpleController{},"get:GetFunc;post:PostFunc")
