* created a distinct expression tree for the static model (thus giving better sharing of sub-expressions and better computation of temporary terms for the static model)
* for that purpose, created StaticModel and DynamicModel classes (ModelTree still persists, but only contains code shared between StaticModel and DynamicModel)
* removed sparse static file (to be later replaced by new algorithm for steady state computation on large models)

* fail if solve_algo=0 and we don't have the optimization toolbox (or under Octave); the previous behavior was to fallback on solve_algo=1
* fail if solve_algo is not between 0 and 4

* when solve1() fails on a block, immediately return with info=1 instead of trying to solve subsequent blocks
* added debug messages

* added a function matlab_ver_less_than() for testing Matlab version
* updated dynare_config.m and build_matlab.m accordingly
* removed tests to check whether we are older than Matlab 6.5 (R13), since we don't support those old versions anymore
* removed a few unnecessary uses of eval()
