Fix "ant" builds

Minimize the number of steps needed to run a scripted build, and
document them in README.md.
README: Tweak grammar/wording and formatting
external: Add new multiarch iptables build (v1.4.20)
external: Add multiarch busybox build
external: Add multiarch nflog build
gitignore: Update for native (external) binaries
external: Remove old packages
README: Add instructions for building native binaries
res: Add new multiarch binaries
Api: Install new multiarch binaries

Check Build.CPU_ABI to determine whether to install ARM, x86, or MIPS
binaries for busybox/iptables/nflog.  Also, store a new "appVersion"
shared preference so that we know when the app has been upgraded.
On each upgrade (and only after an upgrade) we will check to see if
the native binaries need to be updated.
afwallstart: Switch from iptables_armv5 to iptables
res: Remove old ARM binaries
Api: Clean up iptables/busybox binary selection

Now that we have builtin iptables and ip6tables binaries for all
architectures, allow the user to enable them even if the device is ICS+.
Default is to use the system binaries for ICS+ (as before).
