Replace all ZERO and memset with C++11 brace-initialization. 

This will allow us to use non-POD classes inside these objects
in future and is otherwise functionally equivalent, as well
as more concise.

Note that there are some subtleties with handling of
brace-initialization. Specifically:

On aggregates (e.g. simple C-style structures) using an empty
brace-initializer zero-initializes the aggregate, i.e. it makes
all members zero.

On non-aggregates an empty brace-initializer calls the default
constructor. And if the constructor doesn't explicitly initialize
the members (which the auto-generated constructor doesn't) then
the members will be constructed but otherwise uninitialized.

So, what is an aggregate class? To quote the C++ standard
(C++03 8.5.1 §1):

An aggregate is an array or a class (clause 9) with no
user-declared constructors (12.1), no private or protected
non-static data members (clause 11), no base classes (clause 10),
and no virtual functions (10.3).

In SolveSpace, we only have to handle the case of base classes;
Constraint and Entity have those. Thus, they had to gain a default
constructor that does nothing but initializes the members to zero.
