Add consolidated support for custom names

[diwako]

Removal of ACE_name querying.

Instead consolidated custom names possible with variable diwako_dui_main_customName

Personally I use this, and would be sad to see it go.

The main reason why this change is made is to counter the "Error: no unit" names that several people report. It is a weird phenomenon that just happens and it is impossible to track. Instead we offload it to a new variable which is not in use normally. All you have to do is just write a new variable onto the unit if you need.

besides, custom names were not yet possible for nametags, one reason why it was discovered for ACE_name being the issue was, namelist showed up wrong, but nametags showed up correct.

Ah ok, we don't use the radar / namelist so we never noticed any issues there. I'd still rather just use ACE_name rather than having to track more variables but if you have to do it then /shrug

Yeah same. But the issues are just too flaky. I never managed to reproduce it, no one I know with dev skills had those issues. The issue are mostly in units with people without actual dev skills, so it was never possible to debug properly.
