[2/13]msctf: implement SetFocus and GetFocus

[Aric Stewart]

Humm, I thought so at first also, but then when I was testing with word 
2007 (which is the only program I have found so far that uses this) I 
found that if i released here then the DocumentMgr was prematurely 
destroyed and caused Word to crash.   With not releasing then everything 
lined up.

There is also a note in msdn about AssociateFocus which states that it 
does not increment the lock possibly in contrast to SetFocus.

The documentation on these interfaces is very very sparse.
