[development] Introduce dynamic object translation API (optimize this!)

[Gabor Hojtsy]

Hi,

There were some misconceptions on this list about the motives of having 
a defined list of variables, or the usefulness of t() for user defined 
text translation. So I figured I delve into a complete writeup of the 
challenge of user defined object translation, as well as provide a 
simple patch of our current working concept.

WARNING: we are looking for optimization junkies and ninjas to help out 
there! There is a lot to be optimized, while keeping the API simple, or 
making it even simpler!

But even if you are not into optimization, this issue should shed a lot 
of light on how user defined object translation could work, and why is 
that so much different from simply using t().

Excuse me if I will not tack this issue into replies to all your 
concerns on different ends of the variables refactoring thread.
