EasyCreator:Project:Files:Edit: Can quit file without saving(no warning) - even it is changed !

[hgh-esn]

Hi elkuko,

I've been working around with your fantastic tool for a while and I think this is a bug.

When editing a file, this can be quitted directly without saving. This will result in lost data. !!!!!!!

Solution:
When quitting the editor and the file is being changed, a window must popup, to warn the user.
Also the options "save" / "cancel" should be selectable for the user.

I'd like to respond the same as in #52 here 😉
