Improve version information

[Argafal]

In the support chat earlier there was some confusion by a user which version they were using. They had misread the message on /index.

I agree that this message can be misread when one is not familiar with ahoy and its development cycles. Proposed change below. This patch includes some sort of version information every time and explicitly mentions which development version is being used (where applicable).

This patch also includes the suggestion by @beegee3 made in issue #660.
