Completed a full example of forked tests with grouping

The previous example of how to fork group of tests in different
JVMs was incomplete and not fully working.

a) The "testGrouping in Test" is needed, otherwise the grouping is
   not known to which phase to apply
b) Added a more complete Project definition to explain what the curly
   brackets section refers to and where the settings need to be included

The new complete example works out of the box :-)
Removed redundant semicolon
Making example specific to build.sbt

Adding quick test for #1136.

* Just checks to see if + in version numbers are removed from pom files.
Fix #1136 - Ivy's `+` dependencies not converted to maven style syntax.

* Attempt to convert dependencies that end in `+` into maven-style version range
* if a failure occurs, just use the original version (could be bad...).

Fixes #429 - Add better error messages when credentials are not found.

* Create hackery to inspect registered credentials in the IvyCredentialStore.
* Create a new authenticator which inserts itself *after* the ivy authenticator.
  - Will issue an error message detailing host/realm required if credentials are
    not found.
  - Also lists out configured Realms with a 'is misspelled' message.
  - Ignores proxy-related authentication errors, for now.
Pull in @cunei's suggestion for a more complete Ivy->Maven dynamic revision convertor.

   We attempt to convert these constructs to maven:
   * 1.+
   * ]1,2]
   * [2,3[
   * 1+  - Albeit this one is a heuristic for accuracy.

This should help ivy users which prefer the nicer 1.2.+ syntax.

Also adds tests/improves exisitng tests.
