Lack of ability to customize __extend() function

[Sleepyowl]

__extend() function generated by TypeScript is mostly compatible with inheritance mechanisms used by Backbone and Knockback. However, compared to Knockback extend() function, it lacks a couple of steps which leads to faulty behaviour of view models subclassed from Knockback ViewModel using TypeScript inheritance syntax.

I would like to be able to customize the way TypeScript generates inheritance code so it's possible to use TypeScript inheritance syntax with javascript libraries using their own inheritance patterns.

__extends is specifically implemented this way:

var __extends = this.__extends || function (d, b) { ...

Note the || operator -- if an __extends function is already defined, that one is used instead. If you have a different __extends function you want, you can simply add a function __extends in a script that loads before any TypeScript file to change it.

Thanks for pointing out the obvious thing. I'm ashamed I missed it. :-)
