Downloading new version of Pathway Commons data doesn't work

[TomKellyGenetics]

Previously, I was able to download Pathway commons data with downloadPc (in October 2015) but this is no longer possible with this package:

> results <- downloadPc2(destDir = ".", verbose=T)
URL:  http://www.pathwaycommons.org/pc2/downloads/ 
Error in strsplit(tmp3, ";") : non-character argument

I believe this is due to an error in which the urls for each version of Pathway Commons (v2-9) available are kept as a vector rather than one being chosen as a character. This is a fundamental issue which means that this package has not been usable due to multiple versions hosted by Pathway Commons since at least January 2016.
