Let's do the same for dialogs! (was Re: [Patch] use enum instead of strings for type of math 'hull' inset)

The attached patch replaces hull types like "simple", "eqnarray" with an

Should save a few CPU cycles, be more typesafe and prevent a controversy
in which string format the type should be stored.

I think we should do the same for dialog names i.e. replace

  char const * const dialognames[] = {
  "aboutlyx", "bibitem", "bibtex", "box", "branch", "changes",...

with an enum:

enum Dialog {
aboutlyx, bibitem, bibtex, box, branch, changes...

I am suspecting that the conversion to unicode has broken the dialog 
names lookup.
