Title: Support for license comments /*! license */

Adding support for license statements marked like this:
/*!
license
*/
These will be new elements in the AST, and will always be generated into the minified code.
This fixes #85, #306, some of #275, maybe some others.

I also pass the comments and line numbers out of the parser, by adding extra properties to the AST arrays.
This is useful to those using the parser without the minifier.
