upgrade toolstud.io to PHP

I finally made the decision to move my somewhat popular web.forret.com subdomain, with its collection of web-based calculation and conversion tools, over to its own web site. I will migrate the most important applications to toolstud.io, while also redeveloping them from ASP (yes, I know, they’re that old) to PHP, my current scripting language of choice. I will also try to migrate some applications from tools.forret.com over to here too.

I will also use this occasion to upgrade to all the latest versions of my PHP tool libraries (parsing, mrtg, visualisation) and to a modern layout system (probably Bootstrap).

I took the domain name and the hosting on gandi.net, which is also a first tryout.
