introduce private class for BaseTextDocument.

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.

Moving the logic out of BaseTextDocument for use at other places.

Also fixes a crash when folding code at the very end

Task-number: QTCREATORBUG-2159

We need our very own syntax highlighter in Qt Creator.

Previously it would always jump to the start of the document, since
that's where the newly created text cursor is at the beginEditBlock
call. Avoid this when saving the current editor by starting with the
cursor of the editor.

While reloading a text document, the bookmarks got lost since their
associated QTextBlocks were deleted.

This patch makes sure that before reloading, the bookmarks are removed
non-persistently in the same way as when closing a document, and that
they are restored after the document was reloaded.

Currently, no effort is made to update the location of the bookmarks
based on the way the file changed.

We now support renaming files. The version control system tries first to
rename, if that doesn't support or can't rename the file we do a normal
rename. (Note: git, hg, perforce > 2009.02 support renaming, cvs not.
(perforce untested)). We correctly notify all editors of the renamed
file and tell the project manager to rename the file in the project.

Note: Only the qt4projectmanager knows how to rename files.

Note: renaming folders, moving files to different folders, renaming
.pro/.pri files is not supported. Those things can be later added after
this has proven to work correctly in the simple case.

Also we don't do any actions based on the renaming like renaming
classes, changing include guards or #include lines.

The Parentheses, TextBlockUserData and TextEditDocumentLayout classes
and their member function implementations were spread around the
BaseTextEditor class. Moving them to their own file to make the code a
bit better organized.

on QFileInfo to tell us that a file is not writable, but accept
that the attempt to save a file might actually fail (:-) ). This
solves the NT network domain issue without the insane slowness.

The stuff needs more work. We do not have any UI for failing save
operations when closing creator (other than it doesn't close). Bad.
