support for TokenStreamRewriter.getText(ParserRuleContext)

[petrbel]

The getText method of TokenStreamRewriter now supports ParserRuleContext and TerminalNode as parameter, so one can use

myRewriter.getText("myProgram", ctx);

instead of

myRewriter.getText("myProgram", ctx.getSourceInterval());

Why not combine them into a single pair of methods which uses SyntaxTree as the parameter type?

Do you know what the relation between this and #505 is? I've been working my way through that (but slowly since I haven't needed to use TokenStreamRewriter myself before).

[petrbel]

You're right, SyntaxTree is more general case. Issue #505 is interesting approach - I hope that some day we will be able to modify syntax trees in an elegant way. My commit is more like shortcut for friendlier usage of getText.

Issue #550 is also an issue related to the token stream rewriter so I won't merge this until I looked both of these at once.
