morfete in eval shouldn't rely on accessing the training file

[GoogleCodeExporter]

What steps will reproduce the problem?

if one has no access to the training set,  morfette eval will cause an error 
(morfette: 
GramLab/Morfette/Utils.hs:(299,0)-(327,44): Non-exhaustive patterns in function 
eval)

workaround :  use /dev/null instead of nothing

was morfette eval --ignore-case TRAIN test gold 
if one has no TRAIN run
morfette  eval --ignore-case /dev/null test gold

Hmm, are there many cases when people have no training data, but do have gold
standard test data? For those few cases maybe the workaround is fine.

Just to add something about the lack of training data : 
I've created a very small gold standard for out of domain tagging. So people 
can try to tag with morfette, and 
eventually create some scripts to correct obvious mistakes. So when they 
evaluate agains my simili gold, they 
don't have the training data (real case, that happenned just today)
