Material database improvements

[benn]

I've made some changes to the material database. You can now view your favourite materials - here are mine:

We also show the date next to comments, and have fixed downloading .pigm and .igm files - before they weren't saving with the correct extension - that is now corrected.

There is a leaderboard now too!

I still miss the rank for total dls of materials, but your improvements are still welcome.
How about a (floating) batch for the first three material DB fillers.... maybe this would be sensible to spam of useless mats, but I think it would grow by having a achievement to earn here ;-)

Great improvements ben, but I think you need to do more testing and fixing with the favorite system. When I clicked on 'my favorites' I got linked to the leaderboard. and when I tried to add a favorite, it didn't show up in 'my favorites' list. This was using Firefox 3 on OSX

works fine here on vista 64 with the fox @ 3.5.2

Can you list reproduction steps Dale? It's working ok in ie7, chrome, safari and nicks firefox. There are some bugs with login / logout though.

I think it was a bug related to login/logout.
