Description

In cordova-ios-4.x we have a Bridging-Header.h file for Cordova classes, so this will enable Swift plugins.

However, this is not adequate for Swift plugins that have to use third-party Objective-C libraries for their plugin itself. The plugins need to add the bridging headers to the app's Bridging-Header.h file (by appending to the file we already have).

Firstly, we should never modify the app's Bridging-Header file, it should remain static (modifying this will be problematic for every `cordova prepare` cycle, for multiple plugins).

We should have a feature to merge multiple bridging header files together, and point the SWIFT_OBJC_BRIDGING_HEADER value in build.xcconfig to it.

An example of a Cordova plugin that has this problem: https://github.com/alongubkin/phonertc

This could be an optional attribute in the `<header-file>` tag in plugin.xml:
https://cordova.apache.org/docs/en/4.0.0/plugin_ref/spec.html

I propose something like-this:

<header-file src="Foo.h" type="SwiftObjcBridgingHeader" />
