till, chasd

To the wiki, and to better understading of the problem I recommend this
blog post:

The guy is still working on it, I gave hime some hints, and will give more
after I experiment with the info on fileinfo provided by chasd. (Hey 
man, how do
you know that? I couldn't find that info in any documentation!)

I mentioned a patch:
this was the base, but in the meantime I started using Trac more 
extensively, so:

The same proposal I made, and description of problem:

And the resolution by thomasb
with a hard-coded map, they way I was thinking.

So as I said I'll start digging deeper and experimenting with fileinfo,
to get the best solution we can.

chasd, you wrote
"Hmmm, that made my security radar do a beep. Trusting user input isn't 
always safe."
"First, trusting the mime-type from the client is very dangerous. "

But guys, the security part of this is out of the scope of RC I think...
If the user sends something bogus by playing with the extension, who cares?
There are so many ways to do that without RC. Okay, we should try helping
SPAM and VIRUS filters, but this is their task IMHO.
