Tweaks so everything compiles on typescript 0.9.1-1, add watchTS script, add some references to attributes.ts

Conflicts:
	hawtio-web/src/main/d.ts/angular-1.0.d.ts
	hawtio-web/src/main/webapp/app/jmx/js/attributes.ts
More tweaks for compiling with 0.9.1-1, also update the watchTS script to build to app.js.
