Show referenced meshes when train.dat is missing

[adfriz]

When loading extensions.cfg if no train.dat present allow it to be loaded. the train cars will stacked at the origin, its better than showing nothing. Also write info message telling player the train.dat missing cause this.

Example train: E5 ver2.00a

I think that as you are right; the "no plugin data" error message alone wouldn't lead we to realize that Train.dat is missing.
Since these are distributed as "outer views" E5's, they are designed to be integrated into the base cab data.
That is why there is no Train.dat file included.
The setup requires the Train.dat file from the F81_tec200's cab data.

X is missing from the static mesh list :)

(Although, looking at animations for the X format is something else somewhere on a todo list....)
