solved inline problems

[Roger Gregory <roger>]

There were some compilation problems with inlines, mostly
with recursive include files.  The .ixx files include
more than the .hxx files had to, this caused some
mutual dependencies.  I solved these by  simplifying
the includes, which was possible in one case, and
with a gross #ifdef hack in another case.  We will encounter
this problem in the future when we try to inline stuff, but
problably not to this degree.
 
IntegerVar & alloc are tied into a lot of stuff and not much is 
setup for them to use, they are required for everything, thus
hacking them into inlines causes problems, because their internals
depend on much more than their interface does.
