ChangeLog: move old part of 0.1b.y out of the way

The new location should hopefully lead to less confusion.
It reflects the actual flow of commits more closely.

 Changelog for series 0.1b:
 
-mars0.1balpha4
---------
-	* First improvements for scalability to thousands of nodes.
-	  Not yet tested with really huge masses of nodes, only
-	  with relatively small clusters.
-	* Merge	fixes from mars0.1stable41 (see there)
-	* Doc update on socket bundling.
-
-mars0.1balpha3.4
---------
-	* Merge	fix from mars0.1stable40 (see there)
-
-mars0.1balpha3.3
---------
-	* Merge	fixes from mars0.1stable39
-	* Major fix: copy was sometimes hanging.
-	* Minor fix: unnecessary delay of metadata propagation.
-	* Performance improvements / bottleneck enhancenemts:
-	  - Lamport clock
-	  - Network
-	  - md5 checksumming
-	* Userspace: faster logfile deletion via cron job.
-
-mars0.1balpha3.2
---------
-	* Merge	mars0.1stable38: now compiles without pre-patch
-	  on certain kernel versions. Please read ChangeLog there.
-
-mars0.1balpha3.1
---------
-	* Minor fix: deadlock on termination of copy thread.
-
-mars0.1balpha3
---------
-	* Some tuning (more to come later):
-	  * Speedup network by better corking.
-	  * New scalable Lamport clock implementation.
-
-mars0.1balpha2
---------
-	* Socket bundling (cherry-picked from mars0.2.y).
-	* Speedup copy processes (sync, logfile transfer).
-	* Speedup bio and md5 checksumming.
-
-mars0.1balpha1
---------
-	* First improvements for scalability to more than 10 resources
-	  per node. Already tested with 128 resources on a pair of nodes.
-	  More improvements to come later.
-	  No functional changes otherwise (from a sysadmin perspective).
-	  Rollback to stable series 0.1 should be possible at
-	  any time.
-	* Include fix from 0.1stable37.
-
-mars0.1balpha0
---------
-	* Minor fix: the 1&1 specific feature set-sync-pref-list was
-	  not used at all. Without it, the limitation feature for the sync
-	  parallelism degree did not work correctly (without leading to harm,
-	  other than optimum sync throughput / performance).
-	  Removed the old _obsolete_ feature (for formal reasons,
-	  this cannot be done in the 0.1stable branch).
-	  Re-implemnented the feature in a very simple form,
-	  which is hopefully "obviously correct" now.
-	* Minor feature: please use "marsadm cron" as a fool-proof short form,
-	  in particular at cron jobs.
