Try country-dependent jQueryUI localization files

When we load the jQueryUI, we should check if there's a file with full
locale code (eg ui.datepicker-zh-CN.js) before trying to load the file
with language-only code (eg ui.datepicker-zh.js).
Better representation of method parameters

- Let's try to retrieve the constant names (so that the output won't
  contain installation-dependent constant values, for instance
  DIR_FILES_THEMES instead of '/git/concrete5-5.7/web/application/themes')
- Correctly represent 'empty' values: 0, false, empty arrays are now
  represented as they are (and not as null or empty strings)
