Add support for multipackage apks

[GoogleCodeExporter]

Most of apps have only one package in apk. I don't know, if it is possible 
to build multipackage apk using official SDK, but Vending.apk, for example, 
has two:

{{{
$ aapt d resources Vending.apk | head
Package Groups (2)
Package Group 0 id=1 packageCount=1 name=android
  Package 0 id=1 name=android typeCount=1
    type 0 configCount=1 entryCount=1
      spec resource 0x01010000 android:id/progress_small: flags=0x00000000
      config 0 lang=-- cnt=-- orien=0 touch=0 density=def key=0 infl=0 
nav=0 w=0 h=0 sz=0 lng=0
        resource 0x01010000 android:id/progress_small: t=0x12 d=0x00000000 
(s=0x0008 r=0x00)
Package Group 1 id=127 packageCount=1 name=com.android.vending
  Package 0 id=127 name=com.android.vending typeCount=12
    type 0 configCount=1 entryCount=1
}}}

apktool will throw "Apk's with multiple or zero package groups not 
supported" error, if you try to decode such apk.
