SANS: The mask file reading need to warn about ignored commands

[Nick Draper]

The routine that reads Mask (User) files needs to flag up warnings when, for example, it encounters a command it doesn't understand.

[Steve Williams]

(In [8318]) SANS user files with lines starting with "print" will print a message to the log. Any unrecognised commands produce a warning or throw fixes #2142 re #2160

[Brett Tully]

Works correctly when mask is loaded through the GUI, however, no messages or warnings are present when mask is loaded through a script.

[Brett Tully]

This is similar to ​http://trac.mantidproject.org/mantid/ticket/2160

[Steve Williams]

(In [9502]) Ensuring that warning messages are printed re #2142 and #2160

[Steve Williams]

The following commands (with correct path) should print to the script console. The results log depends on logging level.

from ISISCommandInterface import *

LOQ()
MaskFile(r"C:\mantid\Test\Data\LOQ\MASK.094AA")

[Brett Tully]

Issue resolved.
