fly mode back as a modal operator view3d.fly

- access with the F key, Ctrl+Alt+F in editmode, View->Navigation menu
- camera, perspective & 4split (perspective view only)
- uses modal keymap, (same as 2.4x).
- bugfix since 2.4x, when flying upside down, turning left/right was inverted.
- bugfix for "Align Camera To View", was using deprecated v3d->ofs rather then rv3d->ofs, fixed for NDof fly too. checked v3d->ofs is only used in readfile.c

Todo
- Warping the cursor removed in 2.5, no way to place the cursor in the middle of the view.
- Adding keyframes while in flymode to record the path is missing.
- Not getting MMB mouse release events (used for pan). need to look into why.
