Better dependency installing?

[Nacroni]

A big issue I have with the installation is that the dependency installation takes too much time. How it works right now is that it installs every dependency one-by-one, which takes up a lot of time. In my attempts of installing it on Debian, this can be fixed by installing all of the dependencies in one command. The same thing could be said about Fedora, since it seems that also uses a similar method of installing dependencies one-by-one.

Reading the script, most likely if this were to be implemented then the "|| exit 1" would break and not work.

Another problem with implementing this is that if one package were to become missing or removed, then the entire command would break. But, as of right now that doesn't seem likely to happen.
