Random

Just some random thing.

[This one](https://github.com/emanuele45/Dialogo/commit/da173e074b205c1ae653315e6fea2d30faef092e) was partially asked by @StealthWombat (the bit about splitting the "derived from" to its own value), then as usual I got a bit carried away and tried splitting all the three (prev, next, derived from). It is a bit more code, but it looks more useful (for example if you want to place one of the links on the left and one on the right or things like that), if I'm wrong let me know.
