Handle relation in XML

[BinaryBrain]

Hi,
Since I really needed relations for my project, I did it myself.

Every relation has this form:

{
"tags": {
    "except":"bicycle",
    "restriction":"only_straight_on",
    "type":"restriction"
},
"members":{
    "nodes":[],
    "ways":[
        {"ref":"238239023","role":"to"},
        {"ref":"8019802","role":"from"},
        {"ref":"35297466","role":"via"}
    ]
},
"id":"105752",
"visible":true,
"version":3,
"changeset":19774307,
"user":"Xinfe",
"uid":"167945"
}

Hope you enjoy it!
