Google Analytics Integration

The current static TS file includes all configuration options, plus code for activating the plugin, i.e. that part:

page {
    jsFooterInline {
        200 = USER_INT
        200.userFunc = tx_rsgoogleanalytics->processTrackingCode
    }

    includeJSFooterlibs {

        rsgoogleanalytics = http://www.google-analytics.com/ga.js
        rsgoogleanalytics.external = 1
    }
}

[globalString = _SERVER|HTTPS=on]
    page.includeJSlibs.rsgoogleanalytics = https://ssl.google-analytics.com/ga.js
[global]

I think that it is not desirable for that second part to be loaded all the time, since the PAGE object may not be called "page", people might want the code to be in the header and not the footer (as per the latest Google recommendations). Furthermore when using the asynchronous method, the ga.js should not be fetched using includeJSlibs.

As such I propose to split the TS into 2 files, or even 3: one for the general setup, one for traditional inclusion method and one for asynchronous inclusion method.
