Bugfix for steady;

1.) Fixes cases where model was not truly linear, but Dynare did not catch mistake because fvec and jacob contained cancelling NaN
2.) Use correct error code 22 if NaN appear instead of generic 20

Fix for steady
Do not check for the steady state in diffuse filter mode

Closes #400
fixing bug for shock_decomposition with calibrated model (issue #259)
extended_path is a statement, not a block
dynDate: add missing case to throw error if another char is passed
extended_path: new order and hybrid options (ref #152)

Also add stub in the doc for the new options
Correct a typo when solving an equation containing only lead and current values of endogenous
Fix the problems related to the initialization of ilu preconditioner using BiCGStab and also a bug in the BiCGStab in case of block (without bytecode) model options.
