UI: Fix several messages in the UI

Issues reported by @Joan-Pujolar:

- "Limit the render time (excluding synchronization time).Zero
  disables the limit" [space after dot]
- "Apply modifiers to exported mesh (non destructive))" [two brackets]
- "Make this nurbs surface meet the endpoints in the V direction"
  [trailing space]
- "Number of sample along the [xyz] axis of the volume" [samples]
- "Move strips so transformed strips fits" [fit]
- "Number of time the light is reinjected inside light grids, 0
  disable indirect diffuse light" [times]
- "Size of the shadow pool, bigger pool size allows for more shadows
  in the scene but might not fits into GPU memory" [fit]
- "Sequence strip to used the rendered image of a scene" [using]
- "Override the scenes active camera" [scene's]
- "3D region in this space, in case of quad view the camera region"
  [message unclear, rephrase]
- 'Is current view aligned to an axis (does not check the view is
orthographic use "is_perspective" for that). Assignment sets the
"view_rotation" to the closest axis aligned view' [message unclear,
  rephrase]
- "Input properties of an Gizmo" [a Gizmo]

Own fixes:

- "Can't edit driven number value, see graph editor for the driver setup."
  [This editor was split into a driver editor]
- "Set select on random" ["Select or deselect": "set select on"
  is a convoluted way to say "select something"]
- Rephrase the description for the Set Axis operator as it was hard to
  understand.
- Capitalize "blender" in multiple places.
- "Set cursor selection" -> [Set text selection]
  Not sure what the original message meant, it's unclear and possibly a
  copy and paste mistake from another operator.
- "Retiming Hndles" [Retiming Handles]
- "%s '%s' has category '%s'" [trailing space]
- "TimeCode" [Timecode: the Pascal case doesn't seem to be used for
time codes]
