IK: align BTextView text rect/fix alignment

Browse Source 
Preserve passed in text rect in fTextRext (unless in layout)
and create an internal version fAlignedTextRect which is used
in place of fTextRect. fAlignedTextRext is aligned to fit the
text rect bounds and grows to fit. fAlignedTextRect always grows
vertically but only grows horizontally if wrap is off.

Left-aligned text view's grow right, right-aligned ones grow left,
and center center aligned ones grow out.

Set fTextRect to bounds in _DoLayout().

Reduce left and right padding inside text views from full label
spacing to half label spacing. Unify padding between BTextControl
and BTextView.

Fixing padding also fixes right and center-aligned BTextViews.

Undo extra scrolling for non-left text views from hrev24130 fixing
a scrolling left and right with mouse bug when it shouldn't.

Replace max_c and min_c with std::max and std::min respectively.

Remove scrolling from one instance of BTextView::SetText as it
produced undesired results while editing a scrolled text view.

Set text rect in BTextControl::DoLayout() and ScreenSaver
PreviewView::AddPreview().

Don't add padding if BTextView::SetInsets() is called. Set insets
to 0 in Tracker "Edit name" setting which prevents default padding
from being added. This is so that when you rename a file in Tracker
the TextView appears on top of the file name text with no padding.

80 char limit fixes.

Fixes #1651 #12608 #13796 #15189 #15688
