Update roomservice

- Now able to pull in repos from other org's instead of being limited to just our org

Define your du.dependencies like the example below

[
  {
    "repository": "OmniROM/android_device_htc_msm8960-common",
    "target_path": "device/htc/msm8960-common",
    "branch":      "android-4.4"
  },
  {
    "repository": "AICP/device_htc_m7-common",
    "target_path": "device/htc/m7-common",
    "branch":      "kitkat"
  },
  {
    "repository": "CyanogenMod/android_kernel_htc_m7",
    "target_path": "kernel/htc/m7",
    "branch":      "cm-11.0"
  },
  {
    "repository": "DirtyUnicorns/android_vendor_htc",
    "target_path": "vendor/htc",
    "branch":      "lollipop"
  }
]
