recovery: custom recovery build fixes

Patch by Koush

Extract uboot image creation from core/Makefile

http://memegenerator.net/instance/12495768

This change utilizes BOARD_CUSTOM_BOOTIMG_MK to extract out the Uboot boot and
recovery image generation out into it's own file (approx 130 lines).

This should:
    * Clean up the already huge Makefile and the keep ifdeffyness down
    * Make sure Uboot changes don't effect other builds
    * Extract a lot of code that is only for 3 devices

This depreciates BOARD_USES_UBOOT but BOARD_USES_UBOOT_MULTIIMAGE is still valid.

Boards who use uboot boot images should remove BOARD_USES_UBOOT and add
  BOARD_CUSTOM_BOOTIMG_MK := device/common/uboot-bootimg.mk
to their BoardConfig.mk
(location of the makefile is not finalized)

Conflicts:
	core/Makefile

build: Build with colors

Based on tpruvot/chirayudesai's commits, add some color to stdout
and but make it a little easier to customize. Colors are now mapped to
categories and can be edited in Makefile if you or your terminal's
background color do not like them. Defaults:

host stuff: yellow
target stuff: cyan
install/copy: green
filesystem/images: green
imports/exports/includes/notices: green
deletes: red
complete msg: bold green

Coloring can be disabled with "export BUILD_WITH_COLORS=0"
