bsGradientLabel version 4

Version 4 of the bsGradientLabel control. The code has been rewritten to use the clsGradient class (by Rocky Clark) and Rohit Kulshreshtha's gradient module - it no longer uses msimg32.dll, so Windows 95 users need not complain anymore. Some code redundancy was disposed of too. Also, you can change the angle of two-way gradients. If there are any bugs in the code, please let me know. Enjoy!
