Introducing kqml: QML runtime with initialized KLocalizedContext

Useful for testing scratch files that either directly or via imported modules assume that KLocalizedString domain has been set and KLocalizedContext initialized, so they can rely on family of i18n* functions being available in QML scope. In other words, for loading any real-world KDE QML source file without getting these errors:

ReferenceError: i18n is not defined

This simple application is very similar to qml and qmlscene tools provided by qt-declarative package. But unlike those tools kqml is very minimal, without any of the advanced options, custom containment configs or things like OS X specific platform workarounds. Those things can always be added back later if desired, but so far I personally never heard of anyone who would use any of qml options beyond passing it a single *.qml file. Except… maybe a --slow-animations which we can't implement anyway without including private API bits.

This new tool comes with documentation (man page) and zsh completions.
