Please cherry-pick:

Please cherry-pick:
- introduced list view-scoped backing bean for branch offices, including
  interface, which will hold the list for pagination and filtering/sorting as
  @RequestScoped annotated beans will be reset even on each AJAX requests
- according to the change from "general" (request-scoped) to "list"
  (view-scoped) backing bean, also renamed class fields in converters/validators
- private methods should not throw exceptions as they cannot be tested with
  unit tests
- added new bean helper method renderCountry()
- also include department name in renderEmployee(), if applyable
- moved all receipt/product-related renderFoo() methods away to their own beans
  resulting in lesser conflicts on cherry-picking to other projects
- rewrote bean helper methods "renderFoo()" a bit
- added Accept: text/xml in case of AJAX requests (BalusC, thank you again)
- added validator for branch office's email address
- fixed relative path in project.properties (ops, NetBean's fault?)
- added template for opening times data
- fixed end of all ui:composition tags: > must be in new line to allow easy
  adding (only a line added, not 2 existing modified) of new "imports"
- rewrote admin_basic_data_list.xtml to new way, with global search and details
  p:dialog being dynamically loaded (cool PF!)
- same rewrite for admin_branch_office_list.xtml (still other views like
  edit/delete/assign will be missing)
- remove for="someId" where really not needed (<f:convertDateTime> was already
  within the tag where for="x" was pointing to)
- removed not needed "imports" of XML namespaces
- changed admin_contact_data_min.tpl to p:column (was h:column)
- onPostback had some side effects like overwriting values, still some edit
  views may not work as expected (changer to PrimeFaces)
- added required <h:inputHidden> for primary key handled over from URL
  (edit/delete/assign views again)
- <div class="table-footer"> is discouraged as this is plain HTML and no
  engine-controlled JSF tag
- reformatted over-long JSF/PF tags to have each attribute in its own line
- form-admin-edit-user was incorrect (copy-paste) in a contact view, fixed
- removed no longer used tableStyleClass attribute
- *Created.time handled over to <f:convertDateTime> is maybe wrong, just
  *Created is really okay here
- removed styleClass="submit|reset"
- added process="@form" but this is only a workaround according to BalusC on
  stackoverflow.com (thank you for all your value contributions!!!)
- admin_[show_]<fax|landline|mobile|user>_data.tpl were all still using
  h:column, now fixed to p:column
- moved comment block out of ui:composition, else it will show up in HTML code
  and may even confuse the JSF engine?
- removed some CSS attributes from discouraged custom.css as there is now a
  theme around, include .table* classes
- added a lot more i18n strings
