re #6485

Touches nearly everything unfortunately but is necessary.

Refs #3984 Took the wiki description from every algorithm's wiki page and placed it in a comment in the CPP file (instead of the header file).

Refs #262: Created a more generic CompositeValidator and renamed the old CompositeValidator to CompositeWorkspaceValidator. Added some methods to IValidator for future enabled/visible choice.

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.

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.

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

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

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.
