New Formula: Dynare 4.4.3

Following up on #697, we have created a make install.

Given that we already waited 4 months to have #697 reviewed, I would greatly appreciate it if you could move this up on your priority list.
I guess what you suggest, ```doc.install Dir["doc/*.pdf"]``` would work for the pdfs under the doc directory, but not those under subdirectories. Is this the case?
