SANS Allow user to define a new source of calibration

[mantid-builder]

Original Reporter: Gesner Passos

User request:

Can we put something in the user file to say 
“use the calibration from this file here ..” 
which then gets applied to the SANS runs for  SAM & CAN ?
We may be having to  re-reduce a lot of data sets as we find ways 
to improve the calibration. 

It will be just available through UserFile. A new syntax will be available

TUBECALIBFILE =  file_path

Having this entry, the positions of the detector in the TUBECALIBFILE will replace the positions in the loaded workspace (this will be done before any movement).
