Use QFileInfo::fileName() to get the filename, since that also works
when the original path wasn't canonical.

No empty entries should be added to the completion list, but it seems
like this is what is happening. Maybe this warning will give some more
information about the problem.

sessionUnloaded was sometimes emitted when the session manager was in
an unsafe state (between delete m_file and  m_file = new ...) leading
to crashes when slots connected to the signal accessed the sessionmanager
again. This patch moves the signal emission before  delete m_file.

This adds a way for plugins to tell the cppmodel that for certain files,
the actual contents come from it, instead of reading from the disk.
(For texteditors the cppmodel does that automatically.)
