* Added missing trigonometrics filter operators
This PR adds support to trigonometry operators, allowing to create spider graphs and other geometric shapes with filters.
* Adds the missing trigonometric filter operators
This PR adds support to the missing trigonometric filter operators (cos, sin, tan, acos, asin, atan, atan2), allowing to create spider graphs, [pie charts, donut charts, polar charts](https://ffoodd.github.io/chaarts/pie-charts.html) and other geometric shapes with filters, which was previously not possible without add-ons.
Example :
`[[2]cos[]] = -0.4161468365471424`
See also this radar chart made in wikitext by @saqimtiaz using the new trigonometric operators :

This version of the project is not maintained. I've noted this and added a link to Arlen Beiler's community reference. I suppose it could be deleted entirely, but might be useful for historical purposes?
* add Polish translation
* tweak Polish translations to make certain things moree readable
primarily changed translation of "story river" to keep using the English
phrase, but also some other phraes that were awkward when I used the
translation
* add polish flag icon
* add polish translation notes
* replace 'ukryte tiddlery' with 'tiddlery-cienie'

The problem was that the innerwiki template included the tiddler $:/plugins/tiddlywiki/railroad, which was omitted from the wiki. Unexpectedly, missing tiddlers were rendered by the jsontiddler widget as an empty object {}. The fix is to always include the title when the tiddler is missing.
Also cleaned up the template to remove unneeded tiddlers
* Optimise wiki.sortTiddlers()
* Remove local changes to test-filters.js that have now been made on master
Makes the subsequent merge easier
* Fix bug with numeric sorts of textual values
