Fix leaking FileDialog by issuing Destroy to it after it has been used
This also works around the bug in GTK in its file system tracking/file open dialog that causes a crash when a file (in a directory it is tracking, such as the previous directry where an STL was sliced from) is modified with vim. Steps to reproduce the bug: 1) Slice a file from the GUI 2) vim test.stl in the same directory 3) i hello ESC ZZ 4) if Slic3r didn't crash to a gtk assertion failure, jump to step 2 5) if still no luck, your gtk isn't broken. What version do you have?-)
