Separate the curve fitting algorithms into a CurveFitting library

[Nick Draper]

We need to split the curve fitting algorithms into a separate curve fitting library.

This entails the following:

• Create a new CurveFitting project in the mantid visual studio solution
• Copy all of the settings (for debug and release) from the algorithms project
• Remove any settings from algorithms that no longer apply (eg. GSL link lines)
• Move the cpp and h files over and alter any namespaces etc
• Edit the sconstruct file to add your project to the list (about 1/2 way down).
• Add a sconscript file (copy and edit from algorithms.
• Check it all build in VS and scons.

(In [1553]) Redone file moving using svn move to preserve history. Re #193.

(In [1554]) Removed reference to fitting headers in main.cpp. Re #193.

(In [1555]) Update of properties for main project VS file in connection with creation of CurveFitting project. Refs #193.

[Russell Taylor]

(In [1564]) Changed input properties so that SpectrumIndex refers to workspace index instead of spectrum number and startX & endX refer to X values rather than bin indices. For the gaussian fit, startX/endX default to +-4*sigma away from the peak, where 'sigma' and 'peak' are the initial input guesses. Re #193.
