Update README.md

Adding ia32-libs into troubleshooting section
Added support for boost 1.53
Merge remote-tracking branch 'madadam/master'

Conflicts:
	build-android.sh
Modified README.md

Also removed support for boost-1.53/ndk-androidR7 and
boost-1.53/ndk-androidR8 as I only tested the combination
boost-1.53/ndk-androidR8d
Disabling Std.Atomic inside Boost.Asio.

With flag BOOST_ASIO_DISABLE_STD_ATOMIC inside config/user.hpp.
This is because the STL implementation seems buggy (caused deadlocks).

Did this for all supported boost versions: 1.45, 1.48, 1.49, 1.53.

Also relinked patches from 1.49x(R8b+R8c+R8d) and 1.53xR8d
to a proper patch (they linked to 1.48xR8 instead of 1.48xR8b).
Removed info about supporting NDK r7 from README.

As it seems it never worked. The include paths
only seem to have been set for Crystax's version
of this NDK.
Support for NDK-r8e with boost-1.49.0.
Simplified the script a bit.
Include dirs are no longer passed through command line.

But the paths inside user-config.jam is used instead. Also,
these user-configs are no longer added to boost using patches
but whole files are copyed. Lastly, added support for
NDK-8e x boost-1.53.0
