hgweb: Configurable zebra stripes
With this change, you can set
[web]
stripes=3
to get stripes every three lines (a-la fanfold paper), instead of every
line on source and directory listings. The default behaviour is stripes=1
which generates output similar to current, and you can also turn stripes
off by setting it to 0.
