Jack Conradson 025619bbf1 Improve error message for ln/log with negative results in function score
This changes the error message for a negative result in a function score when 
using the ln modifier to suggest using ln1p or ln2p when a negative result 
occurs in a function score and for the log modifier to suggest using log1p or 
log2p.
