禁用来自subversion客户端的常量升级消息

Most everything about the subversion eco-system makes me happy; however the reminders to upgrade to newer versions of the tools gets annoying.

I know I can dismiss the dialog box and tell it not to remind me but I want to never show the dialog boxes for Tortoise, subclipse, and Ankh.Most everything about the subversion eco-system
