Failed DCT import on Timebank document

[marcverhagen]

You can process a Timebank document with the --dct option:

$ python tarsqi.py --dct 20170317 --source timebank data/in/Timebank/wsj_1073.xml wsj_1073.xml

But in the result the metadata show the DCT retrieved from the document, not the one handed in. This may actually be the right behavior, but that should at least be documented.

In general, the documentation in docs/notes/dct.md is a bit off. Should for example add the dct option to the table for clarification and should mention that a normalized value should be used (actually, I take that back, it is mentioned in tarsqi.py, just need to add it to the manual.

So this is done, but I am leaving the issue open till two changes are made to the manual:

• [x] Update the description on the --source option
• [x] The source option description mentions the --dct, fix that since that is now a true option
