• Adds a logging statement with the number of found tablebases
• Changes logging of config files to increase readability

An example logging output is shown on the following image:

For the record, this PR resolves the code review from #130.

Note: The number of lines that the for loop iterates has to be quite big as the output from the subprocess gets buffered. For every option that we have set so far, we get at least one return statement. And because CrazyAra has a lot of UCI options that will be set (roughly 50), I think 200 is a good upper bound.

Sounds reasonable.
