I reformatted the indent to 4 spaces and renamed the patch directory.

The include files can't be reduced in a sane way, because openjdk-8 patch
provides 3 recipes at once:

* openjdk-8-native - which is provided for Java7 with recipes-core/icedtea7 instead of embedding it into recipes-core/openjdk
* openjdk-8 - provides full JDK for target (compiled j2sdk image)
* openjre-8 - provides the plain JRE (compiled j2re image)

That's a huge difference to the existing icedtea7/openjdk-7 combo, which provides 2 recipes and a dedicated package for openjdk-7-jre which contains some jdk relicts. 

So all 3 recipes includes the include file for the concrete HG URI's and checksums for the given release, then either the native or cross inc for building and they have shared code in common inc. Theoretically the URI's and checksums can be moved into common.inc - but this increases entropy in common.inc for decreasing entropy in directory, but mixing information that don't belong together.

Best regards
