Library Functions

With the new library structure, there is no concept of a current library, however, it has been requested that accessing the currently selected library in the Library Browser is desired. To support this, two new functions, ddsGetCurrentLib and dmbGetCurrentLib, have been implemented (the two are basically the same except for consistency, the dmb function is provided for backward compatibility). These functions return the ddId of the library that is currently selected in the Library Browser; nil is returned if no library is selected or if the Library Browser is not synchronized with any particular form. Code directly accessing the dmbCurLib variable or calling dmGetCurLib might no longer be necessary.
