(In [5104]) All Load*Nexus algorithms and LoadRaw now read the run number and store it in the sample logs of all the matrix workspaces they create. re #1264 fixes #1354

LoadNexusProcessed does not populate the title field correctly. Run the following script to see this. 

raw_wkspace = LoadRaw(Filename="//isis/inst$/ndxloq/instrument/data/cycle_09_1/LOQ49886.raw", OutputWorkspace="loq").workspace()
print "Raw title '%s'" % raw_wkspace.getTitle()
saver = SaveNexusProcessed('loq','loq49886-proc.nxs')
filepath = saver.getPropertyValue("Filename")
nxs_proc_wkspace = LoadNexusProcessed(filepath, 'loq').workspace()
print "Processed Nexus title is '%s'" % nxs_proc_wkspace.getTitle()

It is a problem with LoadNexusProcessed as the HDFView program shows the correct title. A suggested fix is to populate the title around line 200 of LoadNexusProcessed.
