Make DROMEDARY CAMEL's hump visible instead of a face #357

Somewhat related to #339, but this is specific to camels.

All vendors except EmojiOne display U+1F42A DROMEDARY CAMEL as a camel seen from the side, such that its lovely camel hump is visible, and helps distinguish it from U+1F42B BACTRIAN CAMEL.

EmojiOne displays it as a face. It is impossible to tell if it's a dromedary or bactrian camel.
Please conform to Unicode's description, and to all other vendors.
