Extend .gan file import for multiple files

[TobiasWantzen]

Dmitry,

up to now I can only import one .gan file at once. Please extend/enhance the import capabilities of GanttProject to import multiple .gan files at once, so that a user can easily make a big overview gantt file of all his sub-projects, which are maintained in single gantt files for better handling.

This was asked and supported multiple times in the forum:
https://help.ganttproject.biz/t/linking-project-plans-together/1540/7
https://help.ganttproject.biz/t/can-u-include-one-project-in-another/1405
And here’s the ticket for you :-)

Thanks a lot!
Tobias
