Addition of Templates

This pull request includes more file templates and license-headers.

I understand Geany uses a hard-coded list of the license-headers, so simply adding headers with the rest of the licenses will not instantly work. However, I hope that if I add some license-headers that another developer will add them. We should be aware that not all developers use GPLv2 or BSD. In my personal opinion, the Geany project should include other license headers and should continue to increase its list.
