Dbzer0 now has the rblind themes

Hey mateys,

I've been interested in getting rblind into dbzer0 for some time, but after some help by db0, we finally have it!

For those who don't know, rblind is an instance/theme specifically meant for visually impaired people.

To try it out, set the theme in your settings to "Rblind_dark" or "Rblind_light".

Have a great [early] weekend, all of you :p
