Fix: some gridview.dtg sizes are longer than their associated data
Fix: make get_noble_color return exactly 1 QColor

get_noble_color was crashing accessing an empty list
when m_nobles.values() returned an empty list.

If m_nobles.values() returns 1 color return that, otherwise
if it returns no colors or many colors return a default value.

- removed unused attribute experience levels
change role drawing method
