Use . instead of $scriptDir in Java process

[RichardLitt]

In the README, you suggest using $scriptDir as a variable for where the stanford NER parser was downloaded. However, I found it easier to just cd into that directory, and run this:

java -mx1000m -cp "./stanford-ner.jar:./lib/*" edu.stanford.nlp.ie.NERServer  -loadClassifier ./classifiers/english.muc.7class.distsim.crf.ser.gz -port 8080 -outputFormat inlineXML

I think using . is a bit cleaner and easier. Just an idea, this isn't a mandatory change for openjournals/joss-reviews#293.
