took the logo from GPG Tools for Mac OS X as a temporary icon, has a free license
when unpacking assets, ignore vendor-added empty folders 'databases' and 'kioskmode'
include the external build NDKBuilder since Eclipse will freak out without (requires NDK in /opt/android-ndk)
fix Java warnings in com/freiheit/gnupg
turn off gcc optmization on the native builds for now, to aid debugging
updated gpgme to v1.3.2 and removed hacks that are no longer needed
hard code this project to the armeabi APP_ABI since it'll be little project to support other ABIs
added NDK_ABI and NDK_COMPILER_VERSION to support NDK r8b's new compilation options
load GnuPG libs when app starts so they're ready when gnupg-for-java loads
rename NDK lib to match the project name: gnupg-for-java
use prefix=$(LOCAL) for GnuPG libs so the *-config scripts work for building

The GnuPG projects (gpg-error, libassuan, gcrypt, etc.) use their own custom
*-config scripts that are something like pkg-config.  They are meant to be
installed before using, and don't handle cross-compiling well.  So we set
the prefix= to the full path where they exist on the build machine, then
the *-config scripts work for building.

Since Android doesn't use the rpath at all anyway, the shared libraries are
relocatable anyway, as long as LD_LIBRARY_PATH is set to point to where the
shared libraries are installed on the device.
include basic gnupg-for-java fixes from guardianproject/gnupg-for-java
make gnupg/gpgme ./configure use the full path of the programs they want to run

gnupg and gpgme both need to run various support programs like gpg, dirmngr,
etc.  They provide ./configure options for specifying the full path to
those programs.  Since we have to do weird prefix= tricks to get everything
to build, we need to specify the actuall installed path of these programs.
added 'make gitclean' to brutally clean all the git submodules
include the gnupg "tools" in the build since gpgme wants 'gpgconf'
update to npth 0.91 since gnupg now requires it
update to the latest gnupg from master
move the gnupg patch before the Makefile generation since it affects it
added 'make assets' as alias to 'make android-assets'
add rule generate TAGS for emacs/etags
