Remove Duplicate Messages扩展用于ThunderBird 3的补丁
Thunderbird的发展真是够慢的，去年12月就出了3.0 beta1了，现在才出3.0rc1。这一年间每次新的beta版本出来我多试用，一方面是似乎没觉得有多少吸引人的新功能(未认真发掘?)，另一方面是因为lightning等关键扩展不可用的关系，一直没有正式换用v3版本。
这次3.0rc1出来，加上lightning之后试用，觉得基本上可以了，于是正式切换。
但有一个说小不小说大不大的问题让我不爽: 不能删除重复邮件了。旧的Remove Duplicate Messages扩展在v3上用不起来，新的R-D-M Alternative也完全不能工作（AMO上的评价又都还说不错，奇怪）。
今早上着手来解决这个问题，参照R-D-M Alternative的代码来看哪些地方需要修改。结果是搞定了，不过早上的两个多小时都搭进去了， :-)
