Do the project restore for each project directly after opening and only
then processEvents(). A project might be in a intermediate state between
opening and restoring.

It's impossible to use very long names and some clipping
occurs due to incorrect size hints on QLabel.
- Made the popup minimum width depend on the longest
project name entered. (it will not shrink)
- The build and run labels have increased minimum size hints.
- Combobox tooltip will be set to the project name as to
  make it possible to expand long names.

This boils down to the same problem as other calls to qmake, if we don't
pass the target mode, qmake will prepend the current platform as target.

I inverted the shadow because the existing one had no root in
reality. It implied that the contents were raised, but since the
target selector was on top of it this one should also have a
shadow. The new shadow better communicates the order of the
hierarchy as well.

Non selected tabs could end up with the wrong text
color depending on different states.

I did a couple of changes to make these more subtle.
- Moved inside the details widget
- Made them fade in and out
- Hide up/down buttons when not required

Note, there are some pending changes to Qt to disable
the graphicsevent cache that can cause issues when
scrolling items.

We already have it in the projects mode so we might as well

This was unintentionally inverted after translations were
introduced.

By popular request I added a "open project" option.
We don't currently have a way of differentiating project types
from other files so I had to hardcode .pro and .qmlproject
for now.

Themed icons was also added to the new and open buttons.
