changes to 'view selected' operator.

Browse Source 
- near clipping is not used to clamp minimum zoom level in ortho mode.
- view selected applied to a single point (no bound-box volume) just moves the view rather then zooming in.

for sintels face view selected didnt work well for eg: selecting a face at the mouth and zooming in.
