Set item colors in BListView instead of BStringItem

* Fixes #3970 without introducing the bugs from BeOS
* Makes it easy to override BStringItem just to change the text color.
* Makes it easy to implement custom list items using the correct colors.

Style fixes to BStringItem

BStringItem: Set the low color to the list view color

instead of the low color, practically this should make little difference,
just a cleanup.

BStringItem: Tiny style fix

Update StringItem use be_control_look->DefaultLabelSpacing()

Also update the Update() method to take into account the added
spacing.

Thanks Axel and Stippi.

Move StringItem text over 4 pixels.

This is so that it does not get draw flush to the edge of the
list view and there is just a bit of padding between the left
edge and where the text starts. The 4 pixels matches other
places that override the DrawItem() method (like Tracker prefs).

Create and use new list view item colors

* B_LIST_BACKGROUND_COLOR
* B_LIST_SELECTED_BACKGROUND_COLOR
* B_LIST_ITEM_TEXT_COLOR
* B_LIST_SELECTED_ITEM_TEXT_COLOR

Update ListItem's to use menu item colors.

* Selected bg uses B_MENU_SELECTED_BACKGROUND_COLOR
* Selected text uses B_MENU_SELECTED_ITEM_TEXT_COLOR
* Unselected text uses B_MENU_ITEM_TEXT_COLOR

Update BStringItem, but also the custom Listitem code in the
Appearance and Locale preflets.

* add protected accessor for baseline offset to StringItem, as that value is of
interest to derived classes

* Moved class BStringItem into its own source file.
* Changed BStringItem::Update() to set a better baseline offset and height;
this should improve vertical text placement.
* Fixed a bug in BStringItem::Update(): it used the owner to determine the
width, but must use the font passed in instead.
* Coding style cleanup.

Removed StringItem.cpp as its implementation is in ListItem.cpp


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10528 a95241bf-73f2-0310-859d-f6bbb57e9c96

It is accomplished ...
