- We use frameless windows to optimize screen space
- We use the fancylineedit where possible

We now do as much as possible lazy initialisation, e.g only start the
full text search indexer if we really access the search widget. Also
moved the QFutur progress into the search widget. Changed all ctors to
be called without an argument, since we share the help engines from
help manager all over the place. Make use of the fact that we only need
to call setupData on the gui engine if we access the help mode, otherwise
all data is fetched thru the core engine whichs setupData is really fast.

There's an issue with receiving the release event when the mouse is
moved slightly, and also on Linux it is apparently normal to handle
these events on press instead of release. Tested with Firefox and
Chromium.

Use constructor initialization, const.

Only revert stuff that is linked to fast string concat.

This reverts commit e70530c5. It
did break builds on older gcc versions (gcc 4.1.2 64 bit Linux,
gcc 4.0.1 on Mac OS X):

parser/qmljsgrammar_p.h: In static member function ???static int
QmlJSGrammar::nt_action(int, int)???:
parser/qmljsgrammar_p.h:188: error: ???QmlJSGrammar::<anonymous enum>???
is/uses anonymous type
parser/qmljsgrammar_p.h:188: error:   trying to instantiate
???template<class T> struct QConcatenable???
...

doing it in 1.3 as well to avoid possible later conflicts

These .pri files which add to INCLUDEPATH and have FORMS should also add
to DEPENDPATH.

Adding to INCLUDEPATH does not add to DEPENDPATH by default with qmake.
That means qmake may not find headers in those paths and won't
consider them dependencies when compiling the source files which include
them.

This doesn't matter when all the headers in the new INCLUDEPATH are
always present, but when some of them are generated (e.g. from FORMS),
the dependencies are important and omitting them means a race condition
in parallel builds.

Fixes errors of the form:
  ..\..\shared\help\topicchooser.h(33) : fatal error C1083: Cannot open
    include file: 'ui_topicchooser.h': No such file or directory
