Experimental single-JDK build. For a release build, you need JDK 1.7 and only JDK 1.7. The much-hated buildOnJdk is dead.

This may mess up CI for a while, since CI builds using JDK 1.5. Sorry, in advance! Once we've proved that the single-JDK build works, we'll change build.xml so that CI can continue to work on 1.5.
Ant can now build under any JDK. If you run under say JDK 1.6, it wil build 1.5 and 1.6 files but not 1.7. So clearly, if you are building a release, you need to build under JDK 1.7.

Megatest now always builds under JDK 1.7, but runs tests under the requisite JDK.

Require "ant jar" to be run on JDK 1.7. Otherwise 1.7-specific classes will be missing. It's too easy to run it on another JDK by accident. "ant compile" still works on any JDK.

MonetDB dialect.
More MonetDB support, in particular loading instructions in loadFoodMart.sh. I needed to re-organize classpaths in build.xml because MonetDB's JDBC driver is built under JDK 1.7 yet we compile under JDK 1.5.
Fix batch size.
Fix MonetDB dialect for backslashes in string literals.
Get MonetDB's JDBC driver from maven repository.
