ant rules for typescript compile

I extended littleware's ant template with rules to compile typescript (*.ts) files in web projects using this ant-macro posted on stackoverflow. The typescript and yuidoc rules are listed further below.

Littleware's build system just extends netbeans' ant templates with IVY support. Netbeans' ant scripts are designed to support extension hooks that run before and after the different build stages (initialization, compile, package, ...). This is from the comment at the top of a new netbeans project's build.xml file:


    There exist several targets which are by default empty and which can be 
    used for execution of your tasks. These targets are usually executed 
    before and after some main targets. They are: 

      -pre-init:                 called before initialization of project properties 
      -post-init:                called after initialization of project properties 
      -pre-compile:              called before javac compilation 
      -post-compile:             called after javac compilation 
      -pre-compile-single:       called before javac compilation of single file
      -post-compile-single:      called after javac compilation of single file
      -pre-compile-test:         called before javac compilation of JUnit tests
      -post-compile-test:        called after javac compilation of JUnit tests
      -pre-compile-test-single:  called before javac compilation of single JUnit test
      -post-compile-test-single: called after javac compilation of single JUunit test
      -pre-dist:                 called before archive building 
      -post-dist:                called after archive building 
      -post-clean:               called after cleaning build products 
      -pre-run-deploy:           called before deploying
      -post-run-deploy:          called after deploying

...

Anyway - I'm glad for netbeans' extensible ant templates. Littleware's build system could benefit from another rework to better support scala and IVY, but it's good enough for now.

Finally - I also wanted to mention that Ian Obermiller posted on github a typescript brush for Alex Gorbatchev's syntax highlighter. It seems to work great ...

Here are those ant rules I mentioned earlier ...
