New parallel dynare:

1) safe management of remote folder;
2) shh scp (and windows equivalent) commands are concentrated in the master;
3) management of remote crashes;
4) begin building option to interrupt remote processes;
5) better parallel waitbar: pops up only at STARTUP (can be minimized subsequently); adaptive dimension;
