Modify Direct Geometry Inelastic scripts to work for SNS instruments

[Stuart Campbell]

A ticket to track the changes made in order to get the direct geometry energy conversion scripts to work for the SNS instruments.

Will need to be revisited in the next iteration

[Stuart Campbell]

(In [5722]) Altered order of parameters on do_conversion() and convert_to_energy() so that we can make the white_run optional. refs #1491

[Stuart Campbell]

(In [5723]) Add extra clause for .dat files (which will point to event files at the moment) in load_run(). refs #1491

[Martyn Gigg]

(In [5731]) Updated direct ConvertToEnergy GUI to reflect script argument order changes. Re #1491

[Stuart Campbell]

(In [5734]) Sort of works for CNCS now. refs #1491

[Martyn Gigg]

(In [5744]) Remove a print statement that will cause the GUI to think there has been an error. Re #1491

[Stuart Campbell]

(In [5754]) Convert T0 from millisec to microsec and offset bins in opposite direction. refs #1491

[Stuart Campbell]

(In [5839]) Removed time bins from class. Now for events, convert to Et, histogram then go back to tof. Added reading of ARCS/SEQUOIA monitors and call GetEi. refs #1491

[Martyn Gigg]

(In [5847]) Fix problem with empty map file on direct ConvertToEnergy interface. Re #1491

[Martyn Gigg]

(In [5851]) Fix a couple or minor bugs that prevented the convert to energy scripts functioning for ISIS instruments. Re #1491

[Stuart Campbell]

(In [5865]) More hacks for ARCS/SEQ. refs #1491

[Stuart Campbell]

Works as well as it is going to for this iteration.

[Martyn Gigg]

This is sufficient for the current iteration. In the future the hacks will be removed and we'll integrate both approaches as they are very similar.
