Bug 15554

At the moment, ccl.properties is fairly disorganized. Once upon a time, it may have been organized numerically or alphabetically, but that seems to have gone out the window a bit. 

It would be nicer if it followed a similar scheme to https://www.loc.gov/z3950/agency/defns/bib1.html

That is, qualifiers and aliases would be grouped into Bib-1 attribute categories: 

1. Use Attributes
2. Relation Attributes
3. Position Attributes
4. Structure Attributes
5. Truncation Attributes
6. Completeness Attributes
--
Indexdata Extensions:
7. Sort
9. Ranking

In other words, all entries that roughly follow the pattern "Qualifier 1=[A-Za-z0-9]+" would be grouped in "1. Use Attributes". 

Examples: 
Abstract 1=62
ab Abstract

Any 1=1016
kw Any

Likewise, entries following the pattern "Qualifier 2=[A-Za-z0-9]+" would be grouped in "2. Relation Attributes".

Examples:

lt 2=1
le 2=2
eq 2=3
ge 2=4
gt 2=5
ne 2=6

---

That said... maybe it makes sense to group together qualifiers that are functionally similar. Like everything found around the comment "# Koha Local-Use Authority Indexes" or "# Subdivisions".

I'm not 100% sure how we should order qualifier (and alias) entries within their respective Bib-1 attribute categories. We could do it alphabetically or numerically (although some entries use index string names rather than numerical values. Example: Geographic-subdivision 1=Geographic-subdivision).
