Enable Peptide settings / Digestion / Enzyme == None for top-down v delcourt  2021-02-26

Hi Brendan,

I think this is rather an improvement than an issue since it's still possible to get the result by another trick. However, it'd be convenient to have the protease choice to be set to "none" for MS1/MS2 quantification of intact proteins / peptides that were not subjected to proteolysis.

Let me know what you think.
Thanks once again for the magnificent tool you bring to the community.
