EFA#060 Sortorder of lists shall use locale-based collators

[cubitusgh2]

The fix in https://github.com/nicmichael/efa/issues/96 for differing sorting algorithms in different efaBths lists is some sort of dirty hack. The sorting algorithm simply maps any special character to an ascii-based one. For instance ä, á, à, °a (and so on) --> a

Newer java versions (at least java 8 and upwards) support locales much better, and also locale-based collators.

efa should use locale-based collators for sorting tables, boatlists, and autocomplete lookup lists.
