I am not sure why these were here, but I would
like to remove them. Various modules requested
that their loaders come before .txt and after
.java. Comment in change logs does not explain
anything, e.g. image/manifest.mf:

Image data loader install before text one and
after java one.

Everything seems to work fine without these
constraints. Text loader however was trying to
recognize .properties and .dtd, which it clearly
does not own; this should not be necessary. Also
asking text loader to handle text/plain in case
file extension alone does not suffice.
