Curve/Surface Editing

- rename "Nurb" to "Spline" in RNA, eg. bpy.data.curves[0].splines[2].type == 'NURBS'
  from a user perspective spline is a more generic term while Nurb is misleading when used for beziers and poly lines.

- added curve.active_spline property so the python UI can display the last selected curve.
  
- set the active spline when entering editmode (uses first selected spline)
  
- added back Hide Handles as a curve property (removed the global flag), access from the view panel in editmode.
  
- added hide normal option for curve, normal size access for curve and mesh display.

- changing orderU/V, endpoints, cyclic, bezierU/V now work in editmode and calls update functions.

- entering editmode was crashing with text objects

- curve.switch_direction() crashed (own fault from last commit)

- Tkey for tilt was overridden by Toolbar, made Tilt Ctrl+T.

- OBJECT_OT_mode_set check for compatible modes before running - so curves dont try go into paint mode with V key for eg.
