move R__CONFIGUREOPTIONS, only used in TROOT.cxx, from RConfigure.h, which

is included by a large number of source files. The R__CONFIGUREOPTIONS are
now stored in RConfigOptions.h, which is only include in TROOT.cxx.
In RConfigOptions.h also the R__RUBY_MAJOR and R__RUBY_MINOR are stored
and included in drr.cxx. This change only forces a recompile of TROOT.cxx
(and maybe drr.cxx) when doing e.g.:
./configure --enable-roofit
make
./configure
make  [ here we used to compile all dictionaries again as rootcint
        depends on RConfigure.h ]
