2) several imporvments for the link-widget
- it uses now popups, if the link-registry says so for a given app
- new widget to add an already linked entry of an other app (used in PM so far)
- new widget to display a single link to view a linked entry
- based on existing show function the template can be edited in place
- dblclicked widgets will be edited in a popup
- new editor supports not only one grid, but a hirachical tree of widgets
still missing:
- editing and operations of grid rows and columns
- type-specific templates for the popup, to make the options more intuitiv
In the meantime the old editor is still functional
- 2 header-templates left and right from the range-display
- optional nextmatch-line with arrows, search, cats, ... after the rows
link_widget:
- new sub-type link-string
Updateted the documenations and lang-files.
