 Hello,

 The links to a category in waterfall do not use the buildbotURL and are
 not relative.

 We access buildbot with a url like `http://localdomain/buildbot`
 and the category links are made by this code:
 {{{
 <a href="/waterfall?category={{ c }}">{{ c }}</a>  
 }}}
 so we end up at incorrect url `http://localdomain/waterfall?category={{ c
 }}` instead of `http://localdomain/buildbot/waterfall?category={{ c }}`

 A simple fix is to make the link relative.
