Fix Latex Bug in display_estimation_results_table.m

Missing line break resulted in compilation errors
Add comments to make clear distinction between generalized distribution and user-imposed bound
Change minus_logged_prior_density.m to reflect new treatment of estimated and calibrated covariances
Change get_prior_info.m to reflect user-specified bounds. Also corrects LaTeX-code
Merge branch 'master' of https://github.com/DynareTeam/dynare
Clarify prefilter option in estimation
Document treatment of missing observations
Closes #286
Filter out use of loglinear with simulated moments

Does not work because steady state is not logged
Fix option loglinear for stoch_simul.m by also logging steady state.

Must be done to assure correct simulations and output of moments. Cannot be done in the solver itself as estimation performs logging of steady state also outside of solver
Clarify the role of the loglinear option for stoch_simul
Make sure repeated runs of stoch_simul.m with loglinear option do not crash due to logged steady state
Add unit test for loglinear option
Provide more information on the loglinear option and its data treatment
Make sure that estimation works after loglinear option in stoch_simul with initval-block

stoch_simul logs the steady state. Here, it is transformed back
Get rid of redundant initval in fs2000.mod

Was replaced by steady_state-model-block
More explicit commenting of stoch_simul.m related to loglinear option
Remove constant and noconstant options from manual for estimation command

Those options are set internally depending on whether the steady state is zero or not. See http://www.dynare.org/pipermail/dev/2014-January/003655.html
Filter out inconsistent specification of prefiltering when observation equation is not mean zero
Added a routine to test if we are currently estimating a model.
Cosmetic changes.
