Fix ConfigService test. Linux/MAC are more forgiving about opening a file that is still open. Re #1248 

Allow property values within the ConfigService to be changed at run time. Added a function to save the current configuration to a file. Re #1248

the "alien" program to convert this into a .deb package
refs #1253

Does not change the output units.

when loading a INES raw file. Also improvement the information sent to user when an IDF is not found. Refs #1249

Refs #1246

It's now possible to set log scales as the default for plots from the View->Preference dialog re #1231

Move time for deciding on whether to build rpm to 0227 so it is after systems tests have run. Refs #1244

queries the workspace data if an item is expanded. Re #1247

than least squares.

Add implementation of ICostFunctions:

CostFuncIgnorePosPeaks
CostFuncLeastSquares

Also added new attribute to Fit called "CostFunction" which
for now can be set to "Least squares" or "Ignore positive peaks".

It was slow because of min and max y values calculations. Postponed this to just before plotting. fixes #1211

Added support for automatic background estimation to the Mantidplot fitting tool. The tool was modified to improve its manageability. Now the functions are accessed not directly by via handlers which help the bookkeeping. re #1184

 *Add more right click menus for plots (part complete):
  *learning how to do this 1 hour (the code wasn't ours)
  *create the menus, link to their commands and test 4 hours

Updates to various excitations algorithms and scripts to move towards running across all direct instruments. Re #1236

re #1031  X values for bin zero is initialised to zero and  added a new method loadSpectra to LoadRawHelper class .By mistake I checked in LoadRawHelper.cpp in last check-in .so submitting  the header file  with this check-in.

Minor update to SANS script following AddLogEntry change as it inadvertently broke the beam centre finder. Re #1237

re #1122  Idata node is formatted on one line.This is  done by creating the  CanSAS1D XML string using  std::string  and then writing the string to the file.I can't see a way to remove line breaks using Poco::XML
Added  a method to replace XML special characters  with entity reference (e.g."&" with "&")
Also added <SASprocess> node with entries <name><date> <term name=”svn”> <term name="user_file"> to the CanSAS1D xml.

Fix an issue with symbol visibility on machines using ld (linux/mac). Dlopen was not able to find some symbols defined but not referenced in the core Mantid libraries due to the default behaviour for dynamic executables being to only export the symbols referenced at link time. This was causing issues with Group/UnGroup notifications. Re #1224

parameter. Refs #1233.

AddSampleLog() takes a string and adds it to a workspace's sample logs. SANS scripts now save the name of the mask file which can be retrieved with Python like
pWS=mtd['992front_2D'];print pWS.getSampleDetails().getLogData('UserFile').value()
refs #1237

Make UnaryOperation multi-threaded. Also unlocked reading of ParameterMap cache and fix bug in Cache updating code. Re #1226.
