Fix id class mix up and add title to table cells

I have mixed up identifier and class for the analysis and statistics
tab. Cell content that is too long, overflows, is cut down. In order
to get the full content I have added a title attribute.

Change bar chart from vertical to horizontal

I refactored the bar chart diagram code to display the bars horizontal.
Why? Because it is not typical to use a vertical bar charts, unless your
x-axis is for the time dimension.

Remove deprecated files

The accessibility stylesheet has not been used for a long time and
interfered with the new chart styling. Also removed the partial for
weighted completeness which will be based on the completeness one.

Base view for weighted completeness on superclass

Due to their relationship the weighted completeness metric view is now
based on the completeness metric view. More specifically, both are using
now the same view and analysis code.
