Updated pfDotMap to use pfCompositeLF

Also includes some other minor tweaks.
Color scale changes to pfDotMap
Reverted to nboot=1000

Forgot that the CI generated by pfComposite are needed
for the time series plot even though they don't matter
for making the dot map itself (the error estimate used
for sizing dots comes from pfDotMap's own [spatial]
bootstrapping routine.
pfDotMap bug fix
pfDotMap update (pfCompositeLF use and fixes)
