Instead simply pass -mkspec default, which has the same effect.
Fixes a bug with qws mkspecs

Users can specify a S60 SDK root for Qt for Symbian versions
now.

Assignments to CE_SDK in the mkspecs are not quoted, and is therefore
stored as a string list.  Recombine the string list back into a single
string before use.

in case one has set MAKESPEC but does not actually pass it as argument.

That is we actually parse the mkspec and evaluate QMAKE_CXX (and a few
other variables) to figure out the correct mkspec. This makes using
custom mkspecs easier and is also cleaner. I also changed mkspec() and
mkspecPath() to behave a little diffrent, essentialy mkspec() will
return only the name (the actual dir name) of the mkspec. That is in
general not sufficient for passing on to qmake. mkspecPath() only
returns the correct path to mkspecs/default.
Hopefully I haven't broken WinCE/Maemo/MinGW.

Now that we check for the qmake.exe location rather than for
the path itself, we need to use QFile for the check.

Includes Maemo tool chain, run configuration, run control,
manager, etc.

Adds the DebuggerManager to the object pool. This is ugly, but
nobody came up with anything better on short notice. To be
refactored.

By only providing a qtInstallDir variant

Rationale: The concept of a "Qt Dir" is dead ever since Qt can be
installed. Specifying the qmake location otoh makes it possible to
unambigously detect all parts of a Qt installation.

- Give the controls a tooltip listing file details (date)
- Make building a QtConcurrent task
- Make log window scroll to bottom and pop up on error
- Make the build code pass on error messages about copying the
  source files to the log file
- Clean up the building code string-wise, use QLatin1String and
  translate messages, cache the icons. Use a QSharedPointer for
  the QtVersions in the settings page since they are passed to
  the BuildTask, which may outlive the dialog.
