[Qt-creator] Attention: Some internal things were renamed

[Eike Ziller]

This is a notice to all of you compiling Qt Creator directly from git,
or even hack around it, or even in it.
(If you are merely using a binary package, you may ignore this mail.)

The outstanding task to rename the internal classes/plugin that  
implements "Locator" from "QuickOpen" to "Locator" has finally been  
done.
We have the global renaming tool in the Qt Creator 1.3.0 beta now, so  
that was an opportunity to finally do this boring task :)

What that means for you, is that you'll need to make a clean build.

At the very least you must run "qmake -r" and remove all occurrances  
of QuickOpen.pluginspec and libQuickOpen.* from your lib/ folder (or,  
mac users, from your application bundle). But I don't recommend to try  
that minimal approach, best to remove your shadowbuild directory, or,  
if you are doing in-source builds, consider using "git clean -dxf"  
which removes all untracked files.

"make clean" is *not* sufficient. And I'd suppose even "make  
distclean" isn't.

Have a nice weekend!
