We use the editor manager's way to save modified files now, so the
normal logic for read only files is applied, including the "cancel/save
as/open vcs/make writable" dialog.
Also fixes that it wasn't handled as a "cancel" if the user chooses to
cancel this dialog.

Use the editor's displayName for the window title.
Also there were missing change signal emissions in setDisplayName
implementations.
Moves the actual handling of the window title from Session to
EditorManager (so it now is also done for the hypothetical case of no
project explorer plugin).

We didn't watch the symbolic link itself before, only the final link
target. We are watching the symbolic link and the final link target now.
Ugly hack: We need to work around QTBUG-15522. The inotify and kqueue
based file system watcher engines (Linux + Mac) don't report changes to
symbolic links. The workaround is to use the polling engine *only for
the links themselves*. The only way to force the use of the polling
engine is by using the auto test hook in QFileSystemWatcher.

The mode we currently use is super paranoid about prime checking,
resulting in an unacceptably long key creation time of several minutes.

this detaches the actual variable management from the string
manipulation.

this is less confusing, because it doesn't look like an environment
variable expansion under unix.
the syntax is a hybrid of printf format specifiers and braced unix
variable expansions.

We were handling it ourselves, now we let saveGeometry and saveState do

qtLibraryTarget is only defined if used with TEMPLATE=lib, which makes
it fail in pri files that are used for app pro files. The tests still

TextEditor will now recognize an UTF-8 BOM.

A setting to determine what to do on saving has been added as well - the
options are "Always Add", "Keep Already Present" and (mostly for
completeness) "Always Delete".
Note: if encoding is "System", "Always Add" doesn't work, because there
is no API to know what the System encoding is.

* Editor manager should abort closing core, if there's a ICoreListener
that aborts closing of a editor.
* Don't save state of temporary editors, and don't save them as open in
  a splitter. So restoring the editor manager state won't try to reopen
  temporary editors.
