Add support for tag in View XML files that would simply output the code from the body of the element into the auto-generated controller.

JIRA Ticket: https://jira.appcelerator.org/browse/ALOY-1700

Code can be added by src attribute:

<Script src="/code/myfile.js" />

By body text:

<Script>
// this is a test
var a = 123;
</Script>

Or by both:

<Script src="/code/myfile.js">
// this is a test
var a = 123;
</Script>

In the last case, it will put the code from the source file above the code from the body text.

The code will then be added to the auto-generated code that is put into the JavaScript controller.
