Date-Time-Group is missing for multipoint objects on the map

[harrywipperfuerth]

Currently, the display of Date-Time-Group (DTG) on the map for multipoint objects is only performed for those, where time is to be displayed within a space according to MILSTD-2525C.

For all other multipoint objects (e.g. lines, corridors, areas, etc.) the DTG is only visible in the properties window, but not on the map.

However, the tactician needs a display on the map even for these objects!

For now, only the text modifiers are displayed on the map where 2525C explicitly mentions them for a certain feature.
Applicable modifiers, their placement and format in 2525C is by no means consistent.
We can think about generalising this for a set of modifiers (say DTG, i.e. W/W1 and unique designation T/T1).

Therefore we would need some 'rules'

• Which modifiers must be displayed for a given feature/geometry
• Where should the modifiers be places (lines, areas, ...)
• How should modifiers formatted, e.g. 'W - W1', or multiline or 'From: W, To: W', or 'Effective from/to', and so on
