allowing glob patterns in Contrasts.ConditionList and DummyContrasts.Contrasts

[Remi-Gau]

As this allowed in the design matrix, it would be handy to have it for the defining what goes into the contrasts.

Ran into the issue when working on bids-standard/model-zoo#14

One part of this tuto just does a very simple F test on the realignement parameters that are entered into the design matrix as trans_? and rot_? but then have to be entered in the contrasts as rot_x, rot_y, rot_z, trans_x...

I agree that these should be available for any place that uses variables.
