Updated instrument selector to understand instrument techniques. Now defining a list of techniques within the widget will cause it to show only those instruments supporting that technique.
Also updated ConvertToEnergy interface to use the new widget. Re #1400 and #1401

Refs #1313: fixed a bug with Event histogramming when the first event TOF was smaller than the first bin. Also, should fix test build that refs #1357.

Added some code to Normalize to make it compatible with ISIS and added some ISIS compatibility comments re #1421

Refs #1455: fixing build errors by modifying the Version() function of the algorithms in UserAlgorithms and ICat

Refs #1455: on Linux, at least, qtiplot build raises many many warnings when a function returns a const int; changed Algorithm's version() function to return just an int. These raise 'type qualifiers ignored on function return type' because the const on the return value is superfluous, according to: http://stackoverflow.com/questions/1134237/pedantic-gcc-warning-type-qualifiers-on-function-return-type 

re #1317 - New menu item  and user interface for MyDataSearch is added.Added a new button to investigations details  user interface to select all files and 
a check box to select only data files.Now multiple data files can be downloaded and loaded to mantid from the ICat interface.

re #1317 -Created new algorithm for MyDataSearch which gives the investigations for the logged in user.
DownloadingDataFile  algorithm has changed to download all the selected files and search algorithm has 
changed to add search by keyword and search by start and end dates.

Refs #1456: something needs to be added to LoadPixelMap to warn if a bad file is fed as input, but I'm not sure how to determine that.

Move the detector to its Z position as part of the load to streamline the reduction steps. Re #1421.

Added a check for the original filename matching and made the error message a bit clearer. Refs #100.

Refs #1456: commented out two std::cout lines that make the build report think the test failed even though it did not.

Refs #1456: filling the spectraMap took forever because of incorrect max pixel_id found; this check-in is a safety check but not a permanent solution.

Modify LoadSpice2D loader to store sample-det distance as instr parameter so that Load() can be used. Re #1442

Flip the paths around so the release directory definitely gets picked up first regardless of the current paths. Re #1401
