provide table columns as scores

[sgratzl]

In the current version, the initial LineUp table shows certain columns. e.g. for genes. In addition, a view are already prepared.

However, when uploading a custom dataset these columns aren't available. So just load the minimal subset of the table that is initially shown and everything else load as score. + the minimal subset of columns also as scores which are hidden since the description in the table already exists.
