Ft2fiff

In reference to http://bugzilla.fcdonders.nl/show_bug.cgi?id=2036#c15
this commit had a complicated story. It should've been in the master branch, but it got overwritten by this commit:
80474e6565fe14b0a35adff7fd7ab34b19844824

This new commit should fix that. I don't have the files ready to test. Can you run test_fieldtrip2fiff and see if it works. The old error should not be there anymore:
http://fieldtrip.fcdonders.nl/development/dashboard/r8467/test_fieldtrip2fiff

Can you send me the traceback if it doesn't work and I look into it.

PS: I don't know why this PR says that there are 299 commits, it should only change fieldtrip2fiff.m in two places.
