Files without filters not copied in trans kit

[Former user]

Original [issue 16](https://code.google.com/p/okapi/issues/detail?id=16) created by @ysavourel on 2009-03-09T21:39:14.000Z:

When a set of input documents counts documents without an associated filter (for example a .png or a .css file), those files do not get passed on to the translation package. They should be copied at the proper relative location so the translatable file could be viewed with their proper companion files.

Rainbow does copy non-filtered files to the original directory
