Allow adding tags to AndroidManifest.xml from project.xml.

For instance, if you need to use an obscure tag like <uses-permission-sdk-23 />, this change will let you enter it into <config:android /> rather than having to make a template.

<config:android>
    <manifest>
        <uses-permission-sdk-23 android:name="android.permission.ACCESS_WIFI_STATE" android:maxSdkVersion="30" />
    </manifest>
</config:android>

The nesting shown here is all required, and it tells Lime where to put this custom tag. In this case, it will go inside the <manifest /> tag. <application /> and <activity /> are also available, and work similarly.

Resolves #1812.

Oh yeah, and I streamlined ConfigData a bunch. Guess I could split that out into a separate PR.

I believe the versionName and versionCode are no longer required to be used in the AndroidManifest.xml as they are already used in the gradle file itself.

Even sdl doesn't use them anymore.

The documentation doesn't mention them being deprecated, and some of their guides tell you to use build.gradle while others point you to the manifest. I figure we might as well keep them in both places for now, until Google gets their documentation sorted out.
