Corrected version of baselines, trial and test files

[Lucia Specia]

Hi all,

As correctly pointed out by Sowmya (thanks!) there were a few spelling
mistakes in some of the files. We've corrected them and to make sure
you won't face any problem we recommend that you download the new
version of the datasets (trial, test and baselines) from the task's
website. No significant modifications were made, the format remains
the same and the results should be pretty much the same too.

Best,

Lucia
