msi: Added comment to describe that install UI level is only in lowest four bits.

[Misha Koshelev]

James Hawkins had a comment on the wine-dev list asking what the 0xf was
in my previous patch that is already in git. I decided to add this
comment per his suggestion. (Wine hacking is fun and addictive :) )

Changelog:

	* msi: Added comment to describe that install UI level is only in
lowest four bits.
