Allow custom descriptions to fully override outside

The station editor allows specifying custom displays, but the custom
value is appended to the hardcoded built-in display. This in particular
prevents sensible use of the display feature provided by the Konstal
105N. It also prevents the user from specifying shorter strings for
displays with length limitation.

This patch adds a al.get_line_display function that returns
linevar_def.train_name (verbatim) if the value is present. The
train_name option from al.get_line_description is removed as this option
would no longer be compatible with other options.

This patchset sequentially removes (IMO questionable) features from
al.get_line_description.
