Synchronizing file extension list throughout the plugin

Hi Toby,

Thanks for adding the extra file images. They look great!

I've synchronized the lists throughout the plugin, so the styles will also work properly.
I also noticed three sets of file images whose extensions were not in the lists: .msi, .sql and .flv. I've added these now.

On another note: when checking the extension list against the images directory, I noticed that the 128x128 PNG images are missing for the following file types:
.air, .ico, .pub, .qt, .ttf and .wav. May be the resize script timed out ?
Would be great if you could add them.

Smile,
Juliette
