allow mime types to be added from the administration settings

[nohalfpixels]

we should allow wp authors to add to the existing allowed mime types right from the dashboard. maybe in the general settings section (or media settings).

i needed to upload a vcard recently and had to create a plugin to update the allowed mime types just for this.

we can make a comments blacklist and maybe this could be handled the same way, one mime type per line, or a comma seperated list?

It would be better to concentrate on adding particular mime types, rather than a confusing and technical settings UI. There is a plugin already that allows for this: ​http://wordpress.org/extend/plugins/pjw-mime-config/.

I would create a separate ticket to propose adding the mime type(s) for vcards. I think it would gain quick traction.
