Updated new in preparation for the 0.0.7 release

+Version 0.0.7 (Mon, 23 Mar 2009):
+  - added support for offline nodes, which are not used as targets for
+    instance relocation and if they hold instances the hbal algorithm
+    will attempt to relocate these away
+  - added support for offline instances, which now will no longer skew
+    the free memory estimation of nodes; the algorithm will no longer
+    create conditions for N+1 failures when such instances are later
+    started
+  - implemented a complete model of node resources, in order to
+    prevent an unintended re-occurrence of cases like the offline
+    instance were we miscalculate some node resource; this gives warning
+    now in case the node reported free disk or free memory deviates by
+    more than a set amount from the expected value
+  - a new tool *hscan* that can generate the input text-file for the
+    other tools by collection via RAPI
+  - some small changes to the build system to make it more friendly;
+    also included the generated documentation in the source archive

 Version 0.0.6 (Mon, 16 Mar 2009):
-  - refactored the hbal algorithm to make it stable in the sense that it
+  - re-factored the hbal algorithm to make it stable in the sense that it
     gives the same solution when restarted from the middle; barring
-    rouding of disk/memory and incomplete reporting from Ganeti (for
+    rounding of disk/memory and incomplete reporting from Ganeti (for
     1.2), it should be now feasible to rely on its output without
     generating moves ad infinitum
   - the hbal algorithm now uses two more variables: the node N+1
