    NIFI-1915 Fixed '$' escape logic.

    Fixed '$' escape logic (if not followed by number) to use Matcher.quoteReplacement(java.lang.String) to
    suppress its special meaning so it could be treated as literal.

> I think the biggest issue is that the text inside of an attribute isn't properly escaped when written to a String, which brings conflict when the text contains dollar signs ($)
> That's a big roadblock for me as I can't predict if and when some $ signs may be present in the data
> An easy way to reproduce is to take the csv to json template here:
> https://cwiki.apache.org/confluence/download/attachments/57904847/CsvToJSON.xml?version=1&modificationDate=1442927496000&api=v2 
> In the first ReplaceText, replace a,b,c,d by a$a,b,c,d (it simulates data that may or may not contain a $ sign)
> Launch the flow, you'll see the errors / warning / infinite loop
