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.
This closes #466.

> ReplaceText infinite loops when attribute contains $ sign
> ---------------------------------------------------------
>
> Key: NIFI-1915
> URL: https://issues.apache.org/jira/browse/NIFI-1915
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 0.6.1
> Reporter: Stephane Maarek
> Assignee: Oleg Zhurakousky
> Priority: Critical
> Fix For: 1.0.0, 0.7.0
>
>
> 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
