Autoconverting Iterables, e.g. for cases like `return new Object[]{hashMap.values()}` (hope this doesn't break anything).
Added special key for converters, `oc:flatten`. If there is only key in the converted table and it has that name, the value of that key will be used directly.
Made filesystem.isLink return the destination of the link as a second value, if it is one.
Merge branch 'master' of github.com:MightyPirates/OpenComputers into master-MC1.7.10
