Play Framework

fix(build): keep IDE project files and test-result directories out of the release zip

The distribution is copied from the working tree, not from what git tracks,
so a git-ignored file ships unless the fileset names it. The 1.13.78 zip,
built in a checkout a Java language server had imported, carried
framework/gradle-plugin/.classpath, .project and
.settings/org.eclipse.buildship.core.prefs, which names two paths on the
build machine, and an empty framework/src/test-result/.

The fileset now excludes .classpath, .project and .settings/ wherever they
are, and test-result/ at any depth in place of the two places it was
excluded at. No tracked file matches these patterns.

Checked by planting the same files in a clean checkout and building: none
is in the zip, whose contents are the released zip's minus those five
entries, plus the skeleton's two dotfiles from the previous commit.
