Add search result tracking with an event

[jdevalk]

Relatively simple method to track searches, using a custom Search event. To make this work, you'd have to setup the Search event as a Goal in the interface. This method will record a pageview to https://example.com/search/ for every search action, instead of logging all those separate URLs, so the only way to find the keywords is within the events.

Fixes #47

@Dan0sz can we also get this into the next version? :)

[Dan0sz]

I don't think so, to be honest. @metmarkosaric what do you think?

[metmarkosaric]

Yeah let's get the proxy out first and then we'll add this in the future release

[masteradhoc]

@Dan0sz @metmarkosaric seems pretty prepared or is here something left beside testing? I can help with that too..

Wouldnt wait another month or two just for sake of seperating this.. especially as this PR (or the former PR) is open for quite some time

[Dan0sz]

We're set to release the Proxy feature any day now. We're not going to add any features last minute, because that would mean having to postpone the release again. And like you said, this PR, as well as other feature requests, PRs and issues, have been open for quite some time.

So, for now, all I can tell you is:

Let me know if you'd like me to refresh this pull.

Hi @jdevalk!

We're working on implementing a self-provisioning API into the plugin, which takes care of all the handy-work around creating custom goals, etc.

@metmarkosaric would this be a cool feature to add in v2.1 (combined with the self-provisioning)?

[metmarkosaric]

yes @Dan0sz, I think this feature is perfect for 2.1

so 2.0 will come with the API and in 2.1 we will implement automatic tracking of all the useful stats such as search terms, authors, categories and woocommerce purchases. could do page types too which is another idea from @jdevalk

hope we can fit it all but would be an amazing release if we do so!

[Dan0sz]

I've fixed the merged conflicts of this PR and pulled it into a new branch. Will add the auto provisioning part there. Thanks for your contribution @jdevalk!
