hello world ^_^
new project struct
only repaint changed area in ellipse effect
rename pixmap to image
fix delete a ptr twice error
Add effect factory

register and unregister an effect is easy
register effect name at start up
disable some effect cause run time error

frame_image is weird
fix crash issue
Add EffectId and remove namespace Effects

If you want to add a new effect, just add new file and without changing
existing files.
update how to
version 2.2.0
maemo and meego files
fix some params of math functions in msvc
Q_EXPORT
add init() to manual register effects

in windows the static vars seems not to be initialized before main.
this will change after NextEffectFactory::instance().registerXXX()?
call NextEffectFactory::instance().init() first. Now you shoud add a
line in init() if you add a new effect.
Back to the previous register method. remove loki.singleton.

It seems that problem is loki.singleton.
It may also cause some weird errors such as using std::vector will crash
on startup.
time.h for msvc
misc
Replace int with EffectId.
