#66 - Revert -docs back to table format and add -detailedDocs

- It turns out the previous -docs implementation was reverted some months ago in the following commit https://github.com/psake/psake/commit/b1d8518c8847f81e54c379dc3445856f31f00a8c to use the original and more compact format-table for output, this is part of the most recent release (v4.3.2).
- This commit adds the -detailedDocs parameter to use format-list for more detailed and list formatted documentation as requested in issue #66
