Merge branch 'master' of github.com:cmrivers/ebola
Liberia sitreps 150 and 151

Note that the 151 source pdf has a wrong number and date on the cover (http://www.mohsw.gov.lr/documents/SITRep%20151%20Oct%2013th,%202014%20(1).pdf)
Also both these source pdf's have a overview table on page 7 (in 'peach' colour) that has cumulative numbers that do not match up with the other tables in each respective pdf. I left those numbers out (they are, generally, higher in the page 7 table).
