imm32: Change the default IME window to better reflect applications request

[Aric Stewart]

First part of this change was proposed by Byeong-Sik Jeon 
<wjsqudtlr at gmail.com>
Use a tooltip window instead to avoid stealing focus from the application.
Additionally respect parameters give to us by ImmSetCompositionWindow 
for placement of the composition window.
