User tracking mod

[mc12345678]

Will this plugin run on ZC 1.5.7?

It appears to be capturing data; however, as session data handling has changed through PHP versions, it appears that there needs to be a little modification to support display of the tracking "history" of a given session... I tried on ZC 1.5.7b with PHP 7.3 and there were a few myDEBUG logs generated at least on the admin side. One was because an array's key did not exist at that time of accessing. The other was because of the session handling issue in trying to show the individual status of user's and the "old" session handling.

During installation, didn't have any logs generated and only came across an issue when I tried to "View" the session history of any of the records. Means, that the plugin could be installed; however, some of the features are not yet fully available immediately until the session "unpacking" is corrected... Will setup a github issue (#4) and try to resolve shortly.

But then... I just accessed it again and it is working fine... *rolling eyes* thinking that *that* issue may be related to my server... Still I plan to look over it a little more anyways...
