ver 0.9.0 issue

[Charles Pegge]

Bstring uses bstr olestrings directly but does not hold them in a garbage collection list. So they have to be deleted explicitly.

Strings however, point to a location in a garbage collection list, which contains the actual bstr.

In this case, the lyrics dynamic array is explicitly deleted (del) in WM_DESTROY. My implementation of del when applied to dynamic arrays, frees each element before freeing the array itself.
