Ancestors: Monticello-ul.728

Do what Monticello-tobe.729 did, but apply the change to MCReader instead of MCVersionReader and remove the unnecessary override from MCVersionReader:

Include a dot when matching against extensions

Packages of extension-less formats (e.g. tonel) will otherwise match for e.g. the MCStReader in MCReader>>#canReadFileNamed: if their name happens to end on an "st", e.g. "Roassal3-Sunburst"
