Remove all references to v8.
Add basic JSRunner Objective-C class.

This links to the JavaScriptCore framework.
Load and execute the javascript files from jjtimer-core.
Introduce global 'App' into javascript.

This is the main 'class' that will be the bridge between js and ObjC.
Add a javascript 'REPL' for testing.

Syntax highlighting would be cool, but seems excessive!
Add an exception handler to JavaScriptCore.

It currently just NSLogs the output.
Add app.js for all the OSX app related javascript.
Rename set_result_text to setResultText.
Add an NSTextField 'timerText'.
Add 'setTimerText' as a Javascript API.
Implement 'setInterval', 'clearInterval' and 'getMilli'.

Currently this uses a single NSTimer, so won't work if there is more than
one user of setInterval.
