Zoph 0.9.9 released

It's been a long time since the last Zoph release. A lot has happened in between, Zoph has moved from Github to Gitlab and a lot of changes have been made to Zoph.

Most of the changes are so called 'refactoring': changes to the code that do not change the functionality, so you shouldn't see anything of it. Many of these changes are necessary to keep Zoph's code up to date with current PHP best practices. Also, there is the long-running change to make Zoph's look fully managed by templates. In this release, I changed more parts of Zoph to use templates, instead of embedded HTML.

There's one exception to the "no functionality changes": I dropped the possibility to redirect zoph back and forth between http and https. When this code was added, 12 years ago, many home-servers were not powerful enough to handle large photos over an SSL session, so Zoph included a system where you would logon via SSL and then redirect back to plain http. Nowadays webservers can easily handle the filesizes and this code only adds unnecessary complexion, so I removed it.

Several bugs were fixed in this version, but none of them very major.
