FStormCamera: allow view distance limit beyond 1 000 000 units

[Sylk]

The clipping of camera view at 1000000 is a problem for me (working with cosmic distances).
Could you add a "far clipping" option, like the "near clipping" option, to break the limit, please? Thanks

Do you have problems with rendering or with viewport?

[Sylk]

Both with previous test, but strangely only with viewport now. Rendering corrrectly shows beyond the viewport clipping.
I will tell you if that occurs again.

[Karba]

I will add far clipping for viewport only.
