Subject: openjdk7: copy over the openjdk7 from openjdk7-branch

The branches differed to much and I wanted to
keep openjdk-6.
We will loose some history, but
I think that is not a great problem

Thanks to khem for working on the recipes too.

+# by adding '-shark' or '-cacao' to the Java command (or by deinstalling an otherwise preferred
+# runtime)
+# 3) All other packages, including -jdk, are optional and not needed for normal Java apps.
