some flexibility improvements

[Zweihorn]

Feature Description

This request would become my personal endeavour and collaborative effort to provide some flexibility improvements to this excellent plug-in. There should be a PR for collecting several commits in due time. In the meantime this feature request could be labelled as "needs discussion", I presume.

However, if you require certain features or functionality not listed here, you can always hire the cosmocode team.

Preliminary Ideas

My preliminary ideas for new features are listed sequentially but without any specific order of priority as follows:

1. New option to deselect the scoring of special page names like e.g., 'sidebar' and '_template'.
2. Make the Quality Summary page accessible to a new qc-manager group besides the existing admin group with config option similar to the existing plugin»qc»adminonly config option.

EDIT - reworked from scratch as I obviously misunderstood some features in the first place.

Hope this helps.

Please note I would provide some documentation after the merge of #59 in due time as applicable.
