- First, Render_opengl inherits from Hook_event, thus Render_opengl should not re-declare members of Hook_event that are already protected, like _core.
 - Second, force Core to wait until the QT engine has initialized the Open GL windows before loading the files. Do this the quick and dirty way by inserting an event loop in the middle of the LAUNCH_INTERFACE case of Core, until initializeGL() has been called.

store the no warning setting in the config file, in order to make it persistent across multiple sessions 

Better fix for the -spn_%d_%d issue with Mac OS X: ignore it at argument parsing time, but pass it to Qt, and lower levels of the stack

  - add a template info.plist
  - add the CMakeLists magic
  - add a fix on main.cpp: Finder passes an argument (-psn_%d_%d) to any bundled app, that Cocoa is supposed to remove, and Qt apparently does not remove. Remove it by hand until someone figures how to make Drag & Drop work with Mac OS X.

- do not display container names which are too close one to another (when vite was opened with 1000+ containers, the display of names was very slow)
- the vertical line now displays the value of all crossed variables at the selected time

- slight correction for drag and dropping of containers

add possibility to switch the order of displayed containers by dragging and dropping them directly in the visualization window. (the father of both containers have to be the same)

add possibility to move around the trace by pressing ctrl, and holding the left button of the mouse while moving it (without drwaing a box or zooming)

addresses bug 13478 : links were not properly handled when several links with the same key (as in otf) were sent in a short time, this modifies the way links are handled to keep track of all opened links, and not only of the last one for each key. If the key is not unique, correlation is made to the first pushed element in the list
