GUI: Extend Protocol panel to include similar features as Options panel, and implement it for MP2RAGE and MTSat

[mathieuboudreau]

This is a TO-DO item to be worked on immediately after the ISMRM deadline.

Per our email discussion, we need to implement a way so that the Protocol panel can be designed in the exact same way as the Option panel is in "Option 2" of the figure below.

Both MP2RAGE (to merge soon) and MTSat need to then be refactored to used this new format for a cleaner GUI and better user experience.

New attribute ProtStyle solves this problem in part (gets rid of buttons) 95694fe.

ProtStyle = struct('prot_namespace',{{'Hardware', 'RepetitionTimes','Timing','Sequence','NumberOfShots'}}, ...
    'style',repmat({'TableNoButton'},[1,5]));
