Added a Basic Log Viewer

[iggi-]

Added a basic log viewer which is able to display a paginated list of the log entries with timestamps and their respective log text.

In the other two cases $results is calculated through $last = $first+$results;, which it could also be here.
That makes it a common calculation that should be made below the if, else if, else - as a common code-path.

There seem to be some formatting issues in general. In general formatting should be consistent with the code around it.
In githubs diff view here you can clearly see indentation issues; did you use tabs rather than spaces (at times)?

Went through it. Seems good.
Thanks for providing this PR! :)
Did not test it yet runtime-wise - just checked the code.

Sorry for the delay, I should have some time this weekend to go over the changes and make corrections as needed.

@iggi- What’s the status? Did you have some time? :)
