Multiple target support

[khlopko]

Currently first buildable target is used for everything, while sending whole list of targets available in the project. Need to add proper support.

On large projects that's critical, as currently it goes through all the targets and tries to get settings for them, but majority of them might be irrelevant. It is also a time consuming operation.
