Codacy looks for ruleset.xml, so give it what it wants.
Bump PMD version to the one used by Codacy, for consistency.

I've left build-installer.xml as a reference for when the installers
are gradled.

Keep them in src for now so ant builds still work (working
clients are good, I'm informed).

Disable some new 'controversial' PMD rules, and enable some of the

A set of ant targets to allow capturing the build output, effectively
grepping through it to find javac warnings from source files, then
outputting a teamcity info file containing the number.

We put them below all other imports, checkstyle defaults to below
each group.

Also fix the formatting of the checkstyle config, replacing tabs
with spaces and fixing broken indentation/spacing.

This was previously all under checkstyle/ which is weird as there's
a whole bunch of non-checkstyle stuff. Move everything into the nice
etc/ folder to keep it out of the way and sanely organised.

- Separate out libraries by their purpose, so Netbeans doesn't have
  so much junk on the main classpath.

- Bundle a version of Ivy instead of downloading it.

- Have Ivy remove old versions of libraries instead of just adding
  new ones.

- Write the classpaths themselves to private.properties instead of
  an indirect private.classpath property which shows up weirdly in
  Netbeans.
