gitweb: blame table row no highlight fix

Until now blame just used the commit/tree/tags/etc style of
highlight-able table rows, which have alternating light/dark rows that
flash when mouse pointer passes over them. This is very annoying in
blame, since the text is static and it interferes with the
per-revision block highlighting.
