Kawa 2.4 released

[Per Bothner]

ftp://ftp.gnu.org/pub/gnu/kawa/kawa-2.4.tar.gz (source release)
ftp://ftp.gnu.org/pub/gnu/kawa/kawa-2.4.zip (binary release)

Nothing major since 2.3, but various tweaks and fixes.

Next, I will merge the 'invoke' branch into 'master' git branch,
maybe as early as tomorrow.  The default for both source code
(in git) and future binary release will be Java 8.
