Alpha 10 - iteration #07:Requirements Nearly Done + Assembling and Building WIP

The display of requirements, if an infrastructure cannot be built or assembled, is finally nearly completed.

The assembling interface is done, only the feedback for assembling duration isn't made yet but this part is a core code shared between the two modes of construction.

The display of requirements for the Building mode is done too, since it is also a shared core code.

I trying much as I can to finalize the whole before January 1st; I need to implement the feedback of the informations to the player and finalize the code linking to the assembling and building processes.

The entire work for this iteration will be done, outside of the debugging of the colonization mission and some small and secondary pre-release additions.
