Moved stable tool tip concept into the BToolManager class.

* This removes the fVisibleToolTip member from BView, and fixes bug #5669;
BToolTipManager::ShowTip() now gets the owner of the tool tip as an extra
parameter.
* Removed the work-around to hide that bug.
* Improved ToolTipTest application to include more test cases like a view that
periodically update its tool tip via SetToolTip(const char*), and one that
sets a new tool tip every second.
* Furthermore, added a test that shows that inner views inherit the tool tip
of their parents.
* Fixed another bug in BToolTipManager::ShowTip() that would release an
extra reference to the tool tip currently shown.

* Added a basic tool tip API, and implementation.
* The BView API can probably be regarded as good enough; the implementation
might need to be improved over time (also, some things as archivability
aren't fully implemented yet). The ToolTip.h header should get public once
finalized.
* Added new B_MOUSE_IDLE message that is sent to a BView after a certain
time has passed (BToolTipManager::ShowDelay()).
* Added small test app (ToolTipTest) that shows what is already working.
