Add specific view for intrinsic precision metric

I will use a specific view in order to be able to highlight misspelled
words and make other adjustments in the future.

Improve implementation for intrinsic precision

My approach was too naive to just call include to see if a text contains
a common misspelling mistake. Hence, I am relying on the word tokenizer
once again.

Switch misspelling test from equal to include

Include is better here, because it is possible, that still characters
are attached to the sliced word. This is the general disadvantage when
using non-whitespace character.

Implement red color highlighting for misspellings

The misspellings are now encapsulated in a span with a class to
highlight the word in red colors.

Fix controller concern names for admin namespace

For the administration namespace I have updated the names, too. Here I
was able to eliminate redundant code as well.
