Support Igraph Version to 0.8

[greebie]

Is your feature request related to a problem? Please describe.

I had some problems brewing the old version of Igraph, so supporting 0.8 could be helpful in an updated release.

Describe the solution you'd like Support for 0.8 since Igraph is being developed pretty solidly right now.

Describe alternatives you've considered Could go back to brew and find out how to install the old igraph.

Additional context

The main difference for graphpass is that the way the fruchtermann and kawada-kamaii algorithms are called has changed.
