Change Qualities using the ToSort column to evaluate their contents

a) NumbersCheck

Context:
The Numbers Check still will detect problems since it analyses based on the ToSort-data. Do we need the Quality when having Number-Protection or can't it be disabled in case number-protection is enabled ?
Anyway, it might be wise to change the programming to not use the ToSort-data anymore
editor_Segment_Numbers_Check, Line 116 ff.

TODO:

the numbers check should not find problems with numbers within numbers tags. Yet if a numbers tag is deleted, it should be listed as error - perhaps best as own tag error category: "Number tag deleted".

b) SpellCheck

SpellCheck also checks based on "ToSort". This must be changed and possibly the offset-Calculation must be adjusted to reflect the changed content/structure. Underlining numbers in areas of spellcheck-problems should be disabled via CSS (if not this effect will be solved by not checking numbers anymore)

This Feature must be implemented based on the number-tag branch obviously. Please contact Sasha to get the correct bramch to fork
