Update to early October data

Pulled the data from the [Liberia Oct 4 Report](http://www.mohsw.gov.lr/documents/SITRep%20142%20Oct%204th,%202014.pdf), typed up the Oct 1 report from Guinea, and fixed a typo in one of the other files. I tried to match my variable names for Liberia to the existing csv's, although there were some additional rows that hadn't been previously reported. Awesome project!
