Remove symbol properties from layer element in .thuban files

[Jan-Oliver Wagner]

Hi,

I have come to the conclusion that it makes sense
to remove symbol properties from layer element in .thuban files:
(these are used for the default values)

Actually, it seems to be better to have always a
classification for a layer and then have
a clnull element describing the defaults.
Else the situation is a bit redundant. Also, the more
complex the description of a symbol becomes the more
the layer element is overloaded. The introduction of the
size element showed this.

Using always a classification would also fix the bug
that labels for default (if there is only just a default
and no classification) are not stored in the .thuban
file.

Opinions?

	Jan
