Model Temperature editing enabled on UI

[Castolus]

Model Temperature editing enabled on UI. This option enables the user to "play" with the model´s spontaneity without having to restart the code every time. Visualization enabled from "settings.yaml". Range of Temperature goes from 0.05 to 0.95 since 0 and 1 are not possible values for this parameter. I didn´t add the rest of parameters (top_k, top_p, etc..) as i belive it´d bee too much info in the UI. But I´m open to do it if you consider it´d be nice.

@Castolus something is still not fully correct. Please run "make check" and "make test" locally.
