SaveNexus and SaveNexusProcessed wouldn't append a record to the history.
This commit fixes that issue and leaves a record on the input workspace so the result is that we get a
complete history, but we lose the execution start time and duration.

This is a quick fix for re #2415. I also rearranged code to make this figure easier to change in future or make dependent on the type of workspace or any of its easily read properties.

Same as last time, will let the windows builds run to get a list of
failing tests on the ISIS build servers; see if it is any different than
the SNS build servers.

Refs #3724: Pulled wiki description text from the wiki site and added in algorithms' header file with special tags. The auto_wiki.py script can retrieve the text to generate the wiki page fully.

Refs #3669: instrument XML contents are saved in NXS processed file. Much more painful then it needed to be.

Fixed tests outside NeXus/DataHandling that relied on loading data
Had to add Nexus as a link dependency for various package Test targets - don't know why!
refs #2822

Refs #2572: Added an initDocs() for all algorithms that sets the summary string to display in the dialog, as well as the wiki summary for possible later auto-wiki-fication of documentation.

Re-enable muon tests. The problem was that the test called the algorithm twice and there were member variables that held state that was not cleaned on re-running. Re #2386.

Refs #1525: Faster save nexus processed for event workspaces, and progress reporting. NexusFileIO class is still a mess though.

Rename Framework code directory to just that. Also delete Main and VS & Eclipse project file. Re #1881.

Refs #1455: on Linux, at least, qtiplot build raises many many warnings when a function returns a const int; changed Algorithm's version() function to return just an int. These raise 'type qualifiers ignored on function return type' because the const on the return value is superfluous, according to: http://stackoverflow.com/questions/1134237/pedantic-gcc-warning-type-qualifiers-on-function-return-type

re #791,#792 added a new virtual function setOtherProperties.This is useful for setting the non workspace properties and period number when group members are processed.

re #697, re# 698 loading and saving workspace groups for nexus files. Roman is fixing the LoadISISNexus failure.  

Remove redundant loggers from Nexus project

Fixing the Linux build failures (forgotten <climits>) and some more algorithm descriptions refs #593 and #410

There maybe still be bugs due to changes to PropertyManager and isDefault() but I've checked all he isDefault() functions now refs #593

re #351. A change to the workspace hierarchy. What used to be Workspace is now called MatrixWorkspace. New Workspace is a base class for MatrixWorkspace and TableWorkspace. TableWorkspace can be stored in AnalysisDataService and passed to algorithms as a property.

SaveNexusProcessed updated. Now writes most required data, but lacking detector spectra map and time series properties.
