Small overdue release

Long overdue release. This is nothing much, really, but I decided to package a release so people using binaries can benefit from the important bug fix below (and to show that I'm still around and taking care of the project somewhat :).

• Fixed a bug where using old in both @Ensures and @ThrowEnsures on a same method would make the instrumenter crash.
• Re-added support for javac option passthrough (thanks to Liam Miller-Cushon).
• Added support for Apache Ivy to retrieve dependencies (I'm still no good with Maven, sorry...).

As usual, these Cofoja JAR files should work with Java 6 and above.

UPDATE (2/7): The new binaries include a fix for an NPE that triggered when running in Eclipse (actually in non-Sun javac).

Cofoja 1.2

This release adds support for Java 8 and introduces a number of incompatible changes.

Feature changes:

• Added support for Java 8 lambdas.
• Removed support for javac options (conflict between Oracle Javac 8 and previous versions).
• Added support for @ContractImport annotation.
• Revamped and updated documentation bundled in the README.md file (documents almost all currently supported features).

Installation changes:

• Now builds with Oracle JDK 8. (Thanks to igoro@)
• Should also build on Windows. (Thanks to igoro@)
• Updated build.xml; now defaults to bootstrap.
• build.xml now requires Ant 1.9.1+.
• Cofoja now requires ASM 5+.

Migration recommendations:

• Pass the classpath, sourcepath and classoutput annotation processor options to Cofoja.
• Set the classpath annotation processor option to the same value as your main project classpath (see build.xml for an example macro using Ant).
• Add explicit @ContractImport annotations where imported names are used in contract code.
