Blackberry 10 Port

This is the initial BlackBerry 10 port.

Currently, UI doesn't have native look and feel because it's based on Symbian Qt Components which were ported to BlackBerry (see README.txt in 3rdparty folder). Unfortunately, Cascades can't be mixed with any other QML components (even with the core ones, like Item or Rectangle) so making native UI means writing it from scratch, which requires much more time and effort. Anyway, I've heard that BlackBerry does accept non-native looking apps into BlackBerry World.

I've also shortly tested the code for regressions on Nokia N9 and Nokia 603 - seems like nothing was broken :-)
