Add query-string driven config

Chickened out of the change to recurse into the replacement. It would not be backward-compatible and it is not worth it. The last commit didn't include the test file with a couple of extra tests to make sure the changes work. I reverted the changes in the test file to allow for recursing into the replacement.

Fixes #2531033 - It will replace everything if not undefined instead of only objects, strings and numbers - Added {LBRACE} and {RBRACE} as possible replacement strings so that braces can be included in the resulting string - Improved the restoration of undefined replacements - Moved RegExps outside of the function

Added Test.Runner.setName

Path corrections and removing trailing commas

substitute has a 'recurse' option to support nested templates (the previous default behavior). Normal operation is now a single level substitution which is tolerant of brackets in the replacement string. [fixes #2526011].
