#1 duplicate timestamps cause confusion in fromage

[jose nazario]

if you have more than one entry with the same
timestamp, you only get to see one of them (the first
one if you sort them by name lexically).

to reproduce:
1. create a bunch of blog entries
2. copy them all under blog_pages, ie "cp tmp/* blog_pages"
!3. reload the page, only the first one lexically shows up
