Instead of in one XML embedded as a resource, now builtin
snippets can be specified on any XML distributed under share.

Provide an interface so users can create/edit/remove snippets.

This was added in the case we start shipping some of the Kate XMLs (still
a pending decision), which should be placed in this dir. However, this
causes a warning when loading qtcreator.pro with master branch version.
So I'll removed it. If we really ship the files it should be re-added
and also the installer notified.

This leaves the code prepared if we decide to ship some of the Kate XMLs (still
a pending decision). In this case the installer needs to be "notified" and the
Kate files put in the repo.

An addition check for actual XML files in the searched directories is also added.

Copy the libs to the application bundle.

Task-number: QTCREATORBUG-1886

Copy them to the .app folder ...

This adds a new "Design" mode that can be used to manipulate qml files
in a visual way. It will only get build if you have the declarativeui
module in Qt.

This is a squashed import from the Bauhaus project. Share & enjoy :)

kinda slower, but without error messages.

use the data copying custom compiler approach here, too.
this leaves more work to qmake, which is good.
on the upside, pluginspecs will be installed when they change without
having force a re-link of the plugin itself.
on the downside, installation of a pluginspec will force a re-link of
the plugin. oh, well - you can't have it all (with qmake) ...

now bin and share are not pegged to linking the executable any more,
but are proper subdirs targets of their own.
unforturnately, qmake is a bit tenacious, so we hack around a bit. :)

more or less in passing by, i removed some superfluous trailing slashes
and added path normalization as well.
