How to handle screen/terminal output

[pbauman]

Right now, there are several different screen-options for controlling when stuff gets output/printed to the terminal. E.g. there are separate options for printing the enable physics, the enable QoI's, EquationSystem info, Mesh info, ... I think I've decided that this is stupid. Because, really, I either want 1. Complete silence (no output), 2. Informative output, and maybe 3. OMFG what's going on output. Also, the vast proliferation of options is a documentation nightmare.

What are thoughts on this? I feel like the majority of the print/verbose/quiet options could be replace with [screen-options] output_verbosity = {0,1,2} or something similar. @roystgnr, @nicholasmalaya, @coreymbryant, I know y'all are starting to/have been using grins, so feel to register your opinion. Anyone else watching this is also welcome to register an opinion.
