Please cherry-pick:

Please cherry-pick:
- let's split project-own and generic i18n strings into separate files so they
  don't interfer anymore with each other, having lesser cherry-pick conflicts
- converted some p:inputText again but into p:calendar for an upgraded way of
  entering some dates (like birthday date)
- nearly (?) all p:selectXxxMenu are now have each attribute in a separate line
  making them better readable
- also they can be filtered
- this whole PrimeFaces thing seem to have one big disadvantage: no more
  NoScript is possible with e.g. pagination, also "select" boxes are no longer
  rendered as <select> HTML tags, but now div, ul and li tags
- also mother PF tags with long list of attributes are now have each attribute
  in separate line. This makes changes lesser intrusive as not the whole line is
  considered as changed (by GIT) but only a line or 2 are just added.
- rewrote branchOffice controller to be fully compatible with sorting and
  filtering as the *same* list must be returned for making this fully working
- added converter of branch office entities for making above fully work (plus
  for many more purpose)
- ignored some text for i18n
