Refs #9059

Refs #3157 Sort our System.h. It was becoming a dumping ground. It should only be touched when absolutely necessary as it affects every file in Mantid. Also combined this with Refs #2345 to sort out DLLExport/DLLImport usage. It's done for Kernel, Geometry and API but stuff in the plugins could do with updating as well.

Modify the SolidAngle calculation for cylinders to EXCLUDE the end caps so that it closely approximates the effects of shadowing for stacked cylinders. Also cleaned up some indentation in renderinging code and made an error message clearer in IPropertyManager. Re #2596

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