Added regular expressions to update the name of svg files included with the AngularJS ngInclude element and attribute

AngularJS allows for the inclusion of svg files in the html as `svg` elements by using the `ngInclude` directive.

Currently, svg files included in the html with this technique are not processed by `usemin` as they don't match any of the regular expressions in `fileprocessor.js`. Consequently their names are not updated in the html after the `rev` phase.

I have included regular expressions that match `ngInclude` directives with an svg image as soure.
