Add configs for cursor images (.cur)

Apply all the configs used for `.ico` files to `.cur` files as the two
image formats are almost identical.

The MIME type for the `.cur` file doesn't matter as browsers seem to
sniff the content. However, `image/x-icon` is specified because it's
the one usually used for `.ico` file and because it's shorther then the
other frequentlly used one (`image/vnd.microsoft.icon`), making the
header size smaller.
