Improved topic relations for a selected set of pages

Following pages are affected by this update:
1. "Functions by Category"
(https://help.libreoffice.org/Calc/Functions_by_Category):
- Added a variable to its heading, so that it can be referenced from
other places
- Removed self-referece in its "Related Topics" (it was turned into
the above heading reference instead, thereby also correcting the
remote HTTP page reference to local help file referece).
Note: Pages already using the reference will auto-ajust (e.g.
"Related Topics" of
https://help.libreoffice.org/Calc/Statistical_Functions_Part_One)
- Corrected "Operators" reference location by moving it into
"Related Topics"

2. "Statistics Functions"
(https://help.libreoffice.org/Calc/Statistics_Functions):
- Added a variable to its heading, so that it can be referenced from
other places (point 6 below)
- Cleaned up references by adding a "Related Topics" section
- Using links to heading variables in "Related Topics", for improved
heading string consistency

3. "Text Functions" (https://help.libreoffice.org/Calc/Text_Functions):
- Added a variable to its heading, so that it can be referenced from
other places (point 5 below)

4. "Add-in Functions" (https://help.libreoffice.org/Calc/Add-in_Functions):
- Added a variable to its heading, so that it can be referenced from
other places (points 5 and 6 below)

5. "Add-in Functions, List of Analysis Functions Part One":
- Added a variable to its heading, so that it can be referenced from
other places (point 6 below)
- Moved "Related Topics" chapter to the bottom of the page
- Using links to heading variables in "Related Topics", for improved
heading string consistency

6. "Add-in Functions, List of Analysis Functions Part Two":
- Added a variable to its heading, so that it can be referenced from
other places (points 2 and 5 above)
- Moved "Related Topics" chapter to the bottom of the page
- Using links to heading variables in "Related Topics", for improved
heading string consistency
