Suggestion: Saved default camera views

[ekolis]

I took to the habit of having 4 camera views open, as in certain modeling apps - one big one that's got a free camera, and then three smaller ones, one along each axis. But the smaller ones keep getting reset to free cameras. It's not much trouble to reset them to the axes every time I open a scene (just press X, Y, and Z), but it is mildly annoying...
