* Fixed a myriad of bugs all over the place, ranging from locking errors to deleting objects that don't belong to the one deleting them (hello HWInterface!) * Almost all ServerWindow cursor stuff was broken; I've replaced all commands to set a cursor with a single one AS_SET_CURSOR. * Renamed some cursor commands. * Changed the (broken) way ServerApp::fAppCursor was maintained - the application cursor is now NULL as long as possible. * Removed superfluous ServerCursor app signature stuff. * The BApplication will no longer duplicate the default/I-beam cursors, it will just reuse the default ones which now have fixed tokens. * As a result, changing the cursor is now working as expected, closing bug #102. * Rewrote Cursor.h, renamed private members to match our style guide. * Minor cleanup. What's still left to be done is reference counting the cursor objects to make them work right and reliable. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16237 a95241bf-73f2-0310-859d-f6bbb57e9c96
