Remove MouseDownThread and its usages

This code comes from an old Be Newsletter and since then the API
received the addition of SetMouseEventMask. In several places the
MouseDownThread was misused: it would spawn a new thread on every mouse
click and not clear the previous one. This could for example lead to
BSpinner skipping values if you clicked it at the right speed.

There are functional changes in BSpinner, before it updated for the
first time 100ms after mouse down, and then as you moved the mouse
around the button, now it activates immediately on first click and then
every 200ms (which may be a bit short). In other places, no functional
changes intended.

PaneSwitch: fix a layout issue with large font sizes

This is used in Find window and also in Installer.

Remove some unused code (I think leftovers from Tracker InfoWindow
refactoring).

Tracker: style fixes to DialogPane

Automatic whitespace cleanup. No functional change.

Style changes in Tracker, no functional change.

Manual whitespace cleanup
Change instances of const char * to const char*
Convert /* */ C style comments to // C++ style comments

More style cleanup.

In some ways, this is unrelated, but I had to combine this anyhow:
* Extend the PaneSwitch BControl from Tracker, so it can draw on/off labels.
This has the added benefit that you can click the label to expand/collapse,
like for example in the Get Info window (Permissions).
* I also added font-sensitivity features to PaneSwitch, and it can be used
in layouted windows (untested).
* This made the "DrawButton" in the Installer superfluous.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30348 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added libtracker.so to the repository and the build.
