Gwibber 中国区登陆twitter，facabook，sina的修改

      最近才换成ubuntu 12.04 。默认界面中有个广播功能，就是gwibber。试了一下，发现twitter，facebook，sina好像都有问题。于是就研究了下代码，python写的很好修改

     关于twitter和facebook都是个https的问题，打开源代码把所有http换成https即可

     关于sina就比较蛋疼了，因为Gwibber里的插件是俺Oauth1.0写的，现在sina换成Oauth2.0了，所以所有认证都要变，所幸api密钥还可以用

     没仔细研究oauth那个库的用法，就直接用requests模拟oauth2.0的认证了，因为自己用，所以删了很多容错的代码

     目前就写了下认证的，api调用的还没写，最近没时间，要赶紧训练了，不然就等虐吧……
