[antlr-interest] StringTemplate 4.0.6 maintenance release

[Terence Parr]

Hi, 4.0.6 ST (java impl) released:

http://www.stringtemplate.org/download.html

This is a bug fix release.

	• STRawGroupDir problem and ST("template") issue. When there are no formal args for template t and you map t across some values, t implicitly gets arg "it". E.g., "$names:bold()$" and bold as "<b>$it$</b>".
	• Fixed https://github.com/antlr/stringtemplate4/issues/5
	• Made fields in the error messages public
