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

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.+

rename node attribute name to label in user input; make node attrbitute label optional, defaults to ID; Double identifier might be problematic, if node label is e.g. gene symbol, then it will be displayed twice in detail information, once as label and once as symbol

layout fixed and working loading nodes and running analysis; still bug with displaying analysis result
