BTextControl:

* Placed _BTextInput_ into BPrivate namespace.
* Made _BTextInput_::AlignTextRect() smarter, it centers the line vertically,
  for the case that the BTextControl has a larger label font. Improved insets
  for asthetics.
* Used _BTextInput_::AlignTextRect() consistently in BTextControl, no more
  custom calls to SetTextRect(). Account for minimum vertical inset of 2
  pixels in GetPreferredSize().
* Consistendly select all text when gaining focus in _BTextInput_.
* Override MouseDown() in case the control did not have focus before, or else
  BTextView::MouseDown() will deselct the text again and place the cursor.
  (in line with BeOS behavior)
* Removed unused fBool member from _BTextInput_ and other cleanup.

BTextView:
* Reimplemented BTextView::_AutoResize() so that it works well with
  BTextControl and autoscrolling when the alignment is not B_ALIGN_LEFT.
  I needed two new members for this, fLeftInset and fRightInset which are
  the original insets from the fTextRects. It might currently be broken
  for renaming things in Tracker, I will have to check. _AutoResize() no
  longer messes up the fTextRect insets.
* Fixed stray carrets sometimes being left over, mostly when auto scrolling,
  but I observed them in other cases as well.
* Prevent negative scrolling offsets when autoscrolling. Fixes weird scrolling
  offsets when navigating to the left.
* Reset scrolling to B_ORIGIN when SetText() is called. Fixes for example
  starting to type in the middle of the control in Vision when entering new
  text and autoscrolling was triggered before.
