It doesn't like the fstream std::string constructor

This will help ensure that for the system tests we can reset the config
once it has loaded and only save keys that we change just in case an old
config was not restored.

on your local developer machine

Ubuntu 11.10 comes with gcc 4.6 and a new warning -Wset-but-unused. Might as well get rid of these now.

Refs #3332 Implemented a send to options tab on the preference dialog where a user can control what programs a workspace can be sent to. Add and Edit buttons open a seperate dialog containing a form with validation to make sure the user enters the correct information.

bug in configservice test.  Tests were affected by values in previous tests.

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.

Added a setFacility()
refs #2760

Refs #2584: new environment variable is not really testable and always fails on windows due to file access errors. Removing test.

Refs #2584: Adding the use of a MANTIDLOGPATH variable to override the log file path at run-time; test.

Refs #2584: Can specify alternative log file path under Linux. Logging configuration should be picked up from Mantid.user.properties better than before.

Fix failing ConfigServiceTest for CMake - it was relying on a relative path existing that (possibly) didn't. Re #1881.

Tell scons to build the new TestHelpers package so that ISIS buildservers are still happy with moving the test helpers while the CMake transition is still in progress. Refs #2196 and #1881

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

re #1691 - adjusting ConfigService to send POCO Notifications on change of a user property. Adding test for this. Adjusting the InstrumentSelector widget in MantidPlot to pick up on these signals and act on them.

Removed references to instrument prefixes which are now handled with the facilities XML file. The MantidPlot config dialog now includes the instrument selector widget rather than a standard combobox. Re #1533
