Internal improvements: better modelling of "sequential/chronological" \ 
sort-tags

This release formalizes the concepts of `sequential sort-tags` vs.
`chronological sort-tags`:

1. A _sort-tag_ is composed of a number of counters, which can be numerical,
   e.g. `123.28` or combined numerical/letter based, e.g. `123ab`.

2. A counter is set of digits (base 10) `123` or a set of lowercase
   letters (base 26) `ab`.

3. A letter based counter can be maximal 2 letters wide. Its maximum is
   `zz` (cf. `filename.sort_tag.letters_in_succession_max`).

4. A _sequential sort-tag_ is a sort-tag that whose counters are at most 3
   digits wide (cf. `sort_tag.sequential.digits_in_succession_max`).

5. The filter `incr_sort_tag` increments only sequential sort-tags.

6. In order not to confuse sequential and chronological sort-tags, it is
   recommended to always write out the year in chronological sort-tags with 4
   digits, e.g. `2013-08-10` or `20130810`.
