QmlDesigner.PropertyEditor: fixing layout issues

There were serious layout issues in the property editor.
While not 100% reliable reproducible they were quite annoying (TASK).

The reason for the issues were the existence of several QtQuickViews and
changing visibility of items.
The pane for Item and the empty pane for no selection use different
QtQuickViews in a StackWidget. Somehow visibility of items is not always
updated properly when changing the QtQuickView in the stack.

Solution: Do not use visibility but stack order instead.
For the layout margins/targets all controls are now always visible, but
unused margins/targets get disabled.

do not look for mkspecs/ directories in project trees

this pretty surprising behavior would interfere with building the
examples from an installed qt tree with qmakes from other qt builds.

.qmake.conf (and .qmake.cache) files provide a possibility to explicitly
"anchor" project roots, so there is no point in having a second, even
more magic way to do it.

QmakeParser: Do not leak temporaries into cache of files

This prevents an access to free'd memory when opening qtcreator.pro.

Looks like qml2puppet.pro gets added to that cache in QMakeVfs::writeFile
with part of the including pro-file's filename in it. That part gets
cleaned when that containing ProFile goes out of scope, leaving a key in
QMakeVfs::m_files free'd but accessible.
