[Lazarus] Project file name nowhere shown

[Hans-Peter Diettrich]

Currently the project title is shown everywhere, instead of the project 
file name. IMO at least Project Options should show the project (file) 
name in its Caption, since the title is shown and editable in this 
dialog. Also the Project Manager should show the project name in its 
Caption, because there the project title typically is too long for that 
narrow window.
