edges in analysis network; handdling of node labels, replacing by chosen identifier if unset instead of netexId; handling of multiple ensg numbers for same node missing

fix dashed legend when colored background; node analysis style half fixed; default nodes style huge somehwoe

added customwebpack as builder; added postcss to add style selector; shadowed necessary styles; switched to other fontawesome angular implementation

add group name changes to legend; the previous change should also remove old nodeGroups and old edgeGroups on config changes from the legend

display drugs and nodes in analysis network; display custom nodes like patients; TODO: node type is not passed on from group AND node style in analysis is not loaded correctly, falls back to default.+
