Also depend on JDT Core 1.9.7.M2

Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>

Before, we used 1.9.7.BUILD-SNAPSHOT, which according to Andy Clement
was originally an intent across a group of Spring projects he was
involved in, to ensure that SNAPSHOTS were sorted alphabetically ahead
of MILESTONEs and ahead of RCs.

If 'name' is identical to 'artifactId' and 'packaging' has the default
value 'jar', we can just remove those tags from the POM.

There were warnings that builds were dependent on the system local
(de_DE in my case). In patterns like "EEEE MMM d, yyyy", parts like day
of week or month names would change otherwise.

- Usage texts are now printed to stdOut, no longer stdErr.
- 'java ...Main -?' no longer prints usage text twice (once to stdOut
  and then again to stdErr).
- AjdtCommand.inferKind: Usage texts are no longer mis-identified as
  warnings or errors just because they contain substrings "warning" or
  "error". Matching is now more precise, looking for "[warning]" and
  "[error]". But in that case the method would not be called anyway
  because errors and warnings are identified in other ways already. As a
  fall-back, the categories IMessage.ERROR and IMessage.WARNING still
  exist in the method.
- In case of compile errors, no usage message is printed anymore,
  because previously the user had to scroll up a lot in order to see the
  actual messages. This is also in line with ECJ. The same is true for
  warnings, but it was like this in Ajc already.
- AjdtCommand.inferKind: There is a new category IMessage.USAGE
  especially for AspectJ usage texts, which will be identified by string
  matching and then correctly handled (i.e. printed to stdOut, not
  stdErr).
- Usage text printing is no longer done in AspectJ but in the AspectJ
  "shadows" fork of JDT. This helps to get rid of some now obsolete code
  here.

Reports explicit boxing, i.e. wrapping of primitive values in objects. Explicit manual boxing is unnecessary under Java 5 and newer, and can be safely removed.

Reports any String.indexOf() expressions which can be replaced with a call to the String.contains() method available in Java 5 and newer.

Reports for loops which iterate over collections or arrays, and can be replaced with an enhanced for loop (i.e. the foreach iteration syntax).
