Fixed a similar issue when Matrix Plot toolbar is not activated when a MantidMatrix gets focus. re #1958

re #1624. Fix issues identified by Michael while using the Rebinning cutter. Namely, the number of bins changing after changing the axis. Also a bug in the SetDimensions vtkDataSet call for vtkStructuredGridFactory, which prevented having non-uniform number of bins in each direction.

 Added some magical code which seems to do the job of getting QMdiArea out of its confused state. re #1958

Add a deb version of the libtcmalloc_minimal package that contains only tcmalloc rather than the whole google-perftools suite. The one in Ubuntu-10.04 is broken so this should allow people to use it. Later distributions come with a working version so don't need a different one. Re #2501

re #2564 - several changes to Indirect* python scripts, most notably fixing an issue occurring with workspace groups in the AbsF2P routines and getting rid of now unnecessary step (since changes to TofCorrection algorithm) in the reduction for TOSCA data.

refs #2566 - adjust TofCorrection algorithm so that it will move the positions of the affected detectors to (0,0,0). This removes the need for us to do this in the python scripting layer and so eliminates a) a very slow step in the reduction for tosca data, b) a fairly large scripting difference between tosca and it's colleagues iris & osiris.

Disable some tests until the required file is added. Also added a removeFile line in a Nexus test. Re #1822

Refs #2572: Ran into issue with un-escaped characters that my compiler did not catch. Commented out all optional messages until I can fix it.

Refs #2568. Fixed the reserved memory calculation on Windows which was return 0. This meant that a workspace went managed even though the reserved memory could have saved it. Also re-enabled the low-fragmentation heap and mmap schemes which weren't being enabled in the right place. I've actually moved them to when the FrameworkManager starts up so that it happens as early as possible.

re #1624. No need to re-load original MDWorkspace as should be available in the analysis data service. Also, enable tests for MDDataObjects.

didn't compile on RHEL6.

Fixes #2561: Sort event list using many cores by default when requesting a histogram. This should speed up showing spectra on un-sorted event workspaces.

Fixes #2452: ThreadPool implementation of LoadEventNexus; speed up can be 20% or so especially if there are empty banks, or no speed-up for other files.
