USB: add support for Dream Cheeky DL100B Webmail Notifier (1d34:0004)
So far the USBLED driver only supports Delcom's "USB Visual Signal Indicator" (http://www.delcomproducts.com/products_USBLMP.asp). The driver generates virtual files "red", "green", and "blue" under the device's /sys/ directory, where color values can be read from and written to. This patch adds support for Dream Cheeky's "DL100B Webmail Notifier" (http://www.dreamcheeky.com/webmail-notifier -- available from several shops, such as http://www.conrad.at/ce/de/product/777048/USB-WEBMAIL). This device isn't as pretty as Delcom's, but it's *far* cheaper, and its 3 LEDs can be set in 32 brightness steps each. The grey envelope contour can easily be removed, leaving a rather neutral white box (with a few small holes), which is useful for generic signalling purposes. Of course, the small circuit board can easily be put into a prettier case. The DL100B device pretends to be a HID, but the HID descriptor shows that it's not overly useful as such (see below). The patch therefore removes the "HID-ness" (hid-core.c, hid-ids.h), and adds the necessary commands to usbled.c. The protocol info comes from the developer's manual that Dream Cheeky kindly provided (815DeveloperManual.pdf).
