refs #6415 #4996 better protection for 0 actions if content tracking is used.

Delay first content tracking request a bit to make kinda sure a possible
previous pageview request is already executed. If there is a new visitor
and there are 2 tracking requests at nearly same time (eg trackPageView
and trackContentImpression) 2 visits will be created as both visitors
are basically at the same time. This is only a workaround and it this
problem might still occur. Also delay a link earlier in case an
interaction is happening to make sure the browser waits for the
interaction to be tracked.
refs #6415 better workaround for possible empty visits

We will now always wait 800ms after a first tracking request was issued.
This should give enough time to create a visitor before any other request
is executed. Ideally we will resolve this issue on the server side as
this problem can occur using other SDKs as well and for some servers or
sometimes the 800ms might be not long enough.

refs #6341 do not extend cookie lifetime on each pageload and expire already after 13 months

instead of 24months. This is the now done by default. If you want different
behavior you can call setVisitorCookieTimeout() manually

#6372 Added events for Piwik update, enable/disable plugin and Plugin Settings update
refs #6415 we have to update cookie timeout whenever the cookie name changes
refs #6341 always calculate the remaining visitor cookie lifetime.

Otherwise the behavior whether lifetime will be extended or whether
remaining will be calculated would depend on the time at which
setVisitorCookieTimeout is called which is very confusing. Also makes
sure in case the page is open for an hour and there is a tracking
request the lifetime will not be extended by an hour.
refs #6341 for consistency set cookie lifetime to 13 months as well
Refs #6372 Textarea Settings value should conserve line breaks
Make TEXTAREA field wider
