Work-in-progress to allow visualizing many vectors at once.
See message on the list, it requires more work before being merged to master but it already looks promising.
Forgot to stage modified files...
Add reset button and remove index pseudo-vector
Improve the multiple vector view:
- no crash
- allow drag&drop of columns
- remove with context menu
Use VectorPtr (smart pointer) rather than Vector * for vector view dialog.
Improve vector view dialog by using a list of vectors. Works well, but I haven't been able to reduce the horizontal size of the
list. Fortunately, it is possible to hide it by moving the splitter to the left.
Allow multiple selection in the _vectorsToPlot widget of the vector page (datawizard).
Apparently a call to reset() is needed. I don't know why as it wasn't like that with the vector selector... But this way it
works at least.
Improve vector view: nicer add/remove buttons and automatic update.
Don't write 0 in cells which should be empty when the vector view is showing vectors of different lengths.
Merge changes for empty entries
Merge branch 'manyvectors'

vector dialog is now stable enough to be merged with master, and used in rolling
packages.
