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.

Because 'cd lib && mvn compile' can now download and (un)zip many
previously SCM-committed third-party dependencies, the following 'lib'
subdirectories have been deleted:
 - ant
 - asm
 - commons
 - jarjar
 - junit
 - regexp
 - saxon
This one is new (but not stored in SCM):
 - jdtcore-aj

For each of them, there now is a .gitignore entry, so as to prevent
developers from accidentally committing the downloaded binaries again.

Get rid of system paths. Instead, rely on JDT Core Shadows to deploy
both binary and source JARs to GitHub Packages. The former module
directory was deleted completely. Instead, the JARs are redundantly
copied into 'libs/jdtcore-aj' in order to be found there by tests and
other Ant scripts.

This module must be a relic from a test runner module once existing
during the Ant build era, but transferred and kept alive in the Maven
build. Actually, it almost doubles build time by running virtually all
tests in all modules again when doing 'mvn test' from the project root.

For now I only removed the module from the root POM, leaving behind
comments there, in the module POM and in the now @Deprecated class
RunTheseBeforeYouCommitTests.

	  	Create a jar file that can be used for load-time weaving...

This allows the correct testing-drivers-all.jar to be built too.

static dependency from weaver classes to runtime classes.
Better than alternative of updating all ant scripts that fork and
the ajc compiler scripts to add aspectjrt.jar into path.

from the aspectjtools jar.

eclipse.plugins. Doh! Easier to change reference in this build
script than fix module name now...

of an aspectj build. Results are placed in:
aj-build/dist/ide/eclipse/xxxxx

Have to build non-all testing-drivers to get testing classes target.
Relies on updated Module.java which trims testsrc but not testing dependencies for testing modules.

(This might be wrong.. still verifying)

- implemented target to fail if bootstrap libraries are out of date
- moved update-tree under setup comment

build-properties.xml has actual version,
Version.java is generated,
and "DEVELOPMENT" is default.
