Fixes known problems with the Excitations interface. This GUI front end now calls generates a call to an existing Python function, which makes changing the behaviour and scripting much easier. Numerical difference with libISIS seem to be fixed. refs #1137 and #841

<parameter name="somefunction:toplevel2" type="fitting"> 
  <lookuptable interpolation="linear" x-unit="TOF">
    <point x="1" y="1" />
    <point x="3" y="100" />
    <point x="5" y="1120" />
    <point x="10" y="1140" />    
  </lookuptable>

update algorithms vcproj

remove deprecated *input algorithms

Added working Nexus test in IkedaCarpenterTest (possible now that workspace parameter map is loaded at the end of LoadInstrument).
Refs #967.

SaveSPE() now flags spectra whose detectors are all masked as invalid. All bins in their spectra take the flag value -10^30 fixes #1140

Further changes to functions, FunctionFactory and ParameterTies in order to be able to save ties to a string from functions and create functions with set ties via FunctionFactory. re #1121

Update Windows installer to add auto complete keywords list. Re #100

rest of the qti import. This will allow qti functions to be used in imported scripts, as 
long as they are run from within MantidPlot. Re #1040

Fix for MantidPlot scripting autocomplete bug under Linux and earlier versions of QScintilla. Also update autocomplete sources so that it uses the current document as well. Re #713

Fix for possible crash when the autocomplete prepare function tries to cancel itself and then rerun. Re #713

Updated http://www.mantidproject.org/InstrumentDefinitionFile in connection with previous commit to this ticket.
Allow parameter to be specified at instrument level and done this for the GEM instrument.
Added more tests. Refs #967.

InstrumentWindow now listens for the workspace replaced signal and updates itself. Re #866 
and #650 

When specifying fitting parameter now can associate fitting parameter with fitting function using notation

  <parameter name="IkedaCarpenterPV:Alpha0" type="fitting"> <value val="0.734079"/> <fixed /> </parameter> 

where IkedaCarpenterPV is the function the parameter is associated with. Wiki not updated yet. Refs #967.

Added the ability to fix fitting parameters specified in instrument definition files. Added tests to FitParameters.
Tested this works params defined in GEM IDF. Refs #967.
